Artificial turf has been a staple in many pro sports stadiums for about 50 years. And while there's no doubt that AstroTurf and its modern equivalent, FieldTurf, have changed the way pro football and baseball have been played, the surfaces have generally been considered safe for athletes to play on.But on Monday, the NFL Player's Association formally called on team owners to "proactively change all field surfaces to natural grass," citing higher rates of injuries to players who are playing on artificial fields.In an open letter, NFLPA President J.C. Tretter — a center for Cleveland Browns in the midst of his eighth NFL season — claimed that most of his teammates preferred to play on grass, noting that his joints felt "noticeably stiffer" after playing on artificial turf."The unforgiving nature of artificial turf compounds the grind on the body we already bear from playing a contact sport," Tretter wrote.In his letter, Tretter wrote that real grass offers more "give," reducing the stress on feet, ankles and knees. He also noted that NFL injury data shows players have a 28% higher rate of non-contact lower extremity injuries when playing on artificial turf.Tretter also noted that despite harsh conditions, cold-weather cities like Cleveland, Green Bay and Pittsburgh still use traditional grass fields. In addition, indoor stadiums in Las Vegas and Phoenix also use grass surfaces."Agronomically, natural grass field surfaces are possible everywhere," Tretter said.As of 2020, 17 of 31 NFL stadiums use traditional grass.Tretter's letter comes weeks after the NFL was forced to inspect the artificial turf at MetLife Stadium — home of the Jets and Giants — after several high-profile players were injured in the surface in the opening weeks of the season. Among those hurt during weeks 2 and 3 of the season were 49ers players George Kittle Nick Bosa, Jimmy Garoppolo and Raheem Mostert.In 2015, Houston's NRG Stadium switched from natural grass to an artificial surface after more than a decade amid player criticism over injury concerns. Due to its retractable roof, groundskeepers grew grass in trays outdoors and then brought the trays indoors and assembled them together with forklifts to form the playing surface. Players claimed the system created seams in the playing surface which led to injuries, and the stadium even faced a lawsuit from a former player who claimed the grass led to a career-ending injury.Tretter's Browns teammate, wide receiver Odell Beckham Jr., was lost for the season this week after suffering an ACL tear while playing on an artificial surface at Paul Brown Stadium in Cincinnati on Sunday. 2649

Another federal judge has overruled the Trump administration's efforts to end a popular immigration program -- this time saying the government has to accept new applications.The ruling on the Deferred Action for Childhood Arrivals program, however, won't take immediate effect, with the judge delaying the ruling for 90 days to allow the administration to make its case.Similar to the other rulings, Judge John Bates concluded that the wind-down of DACA was "arbitrary and capricious" because the Department of Homeland Security failed to "adequately explain its conclusion that the program was unlawful." The judge also accused the government of providing "meager legal reasoning" to support its decision.A George W. Bush appointee to the US District Court for the District of Columbia, Bates delayed the effect of his ruling "to allow the agency an opportunity to better explain its rescission."The DACA program, which protects young undocumented immigrants who came to the US as children, has already been resumed after President Donald Trump sought to end it in September, after two federal judges issued nationwide rulings to accept renewals of the two-year permits issued by the program and after the Supreme Court declined to circumvent the appeals process to overturn those decisions.But while the Department of Homeland Security has been processing renewal applications under those rulings, as the appeals make their way through the courts, Tuesday's ruling was the first to order the program to resume accepting new applications -- potentially opening the program to tens of thousands more immigrants than the roughly 700,000 currently protected.In September, the administration defended ending the program by saying it was likely to fall in the courts anyway, arguing a six-month wind-down of the program would be more orderly than a sudden end brought by the courts. No court has found DACA to be unconstitutional. 1944

America's job market got back on its feet in October.The U.S. economy rebounded from the hurricanes and added 261,000 jobs, the best performance of the Trump administration.Unemployment inched down to 4.1%, the lowest since December 2000.But wages took a step back. They grew only 2.4% in October compared with a year earlier, behind September's number. The absence of better wage growth and inflation is one of the biggest mysteries in the economy.WATCH: How hourly wages fared in the October jobs report 513

An Idaho man says his new 8-week-old puppy appears happy and healthy despite being flown across the country to the wrong airport -- landing in Las Vegas and Salt Lake City before finally arriving in his arms Sunday.Owner Josh Schlaich had vented his frustration with Delta Air Lines on Facebook when the white and brindle puppy failed to arrive Saturday as scheduled and he was unable to get any answers by phone.According to Delta, the dog left Richmond, Virginia, and was due to fly into Boise on Saturday evening, connecting in Detroit and Minneapolis. But Delta says there was a mixup somewhere between Richmond and Boise -- and Schlaich actually received the wrong puppy when he arrived at the airport. Delta is investigating to determine where and how the mixup happened.When Schlaich realized that his dog was missing, he started working with Delta officials to track down his puppy.Schlaich's dog ended up spending Saturday night in a kennel in Detroit. Sunday morning, the puppy was flown to Minneapolis -- but then Delta said it "misrouted" the puppy and it ended up in Las Vegas. The puppy was then put on a plane to Salt Lake City, finally making it to Boise on Sunday night.Delta said the puppy was given food and water and let out of its crate periodically throughout the journey.In his Facebook post, Schlaich said he received a call from someone at the Delta terminal in Detroit about his dog's whereabouts, but then he got the runaround."Was then given the number of the boarding facility -- a disconnected line. Was not given a call back number by Detroit person, and the customer service would not give me their direct line. Tried calling Delta Cargo customer service, only to be yelled at by the rep and hung up on. No idea where my dog is, or what conditions he'll be placed under for the next 24 or more hours. Don't know when he will come into Boise tomorrow. No idea who to call. Absolutely ridiculous customer service."After Delta responded, Schlaich posted two updates to say the dog was delivered and safe."Local Delta reps (in Boise) did their best and were very helpful, but corporate and I will be having a thorough conversation tomorrow," he wrote.Schlaich later said Delta was "working hard to make this right."In a statement to CNN, Delta said it apologized for the mix-up and has fully refunded the dog's shipping costs and started a review of its procedures."We know pets are important members of the family," the airline said.It's at least the fourth airline error involving an animal in a week.On March 12, a French bulldog died on a United Airlines flight from Houston to New York after a flight attendant told its owner to put the dog, in its carrier, in an overhead bin. By the time the flight was over, the dog had died.A United spokesman said the passenger told the flight attendant there was a dog in the carrier, but the attendant "did not hear or understand her, and did not knowingly place the dog in the overhead bin."Tuesday, United flew a 10-year-old German shepherd to Japan when it was supposed to land in Kansas. The dog was mistakenly switched with a Great Dane that landed in Kansas instead.Two days later, United diverted a St. Louis-bound flight to Akron, Ohio, when it realized a pet was loaded onto the flight in error.The-CNN-Wire 3297
