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

As coronavirus cases surge throughout the US, there is an apparent strain on labs conducting tests.Quest Diagnostics said on Tuesday that it is processing 50% more tests per week than at the end of September. This has caused a slight delay in priority tests for high-risk patients and essential workers.“We will continue to expand our physical capacity, with the addition of new testing instruments and related equipment,” Quest said. “We also intend to expand our lab referral partner program. And we will continue to strive to provide the fastest testing for priority patients, which includes those who are hospitalized, pre-surgical or receiving care in congregate settings, such as nursing homes.”LabCorp says it is still processing coronavirus tests in one to two days. The company is conducting 210,000 coronavirus tests per day, but has the capacity to do 300,000 a day.With Thanksgiving just a week away, there is concern that the holiday will cause increased testing demand. In addition, a number of states are requiring visitors to get tested upon entering the state."We are concerned about Thanksgiving," Brett Giroir, the assistant secretary for health at the U.S. Department of Health and Human Services, told ABC News. "In terms of post-Thanksgiving surges and testing, we really are going to create as many tests as possible, of as high quality as possible. Get them to as many people as possible."Massachusetts Gov. Charlie Baker said he is concerned that the holiday in part is responsible for the surge in testing from people planning to travel this Thanksgiving.“It’s pretty clear, based on those lines, that a lot of people are going to travel over the holidays,” Baker said. “And there’s not much, at this point, that we can do other than say we think that’s not a great idea.” 1806

As floodwaters started receding in central Texas, authorities discovered the body of a second victim in this week's deluge.The woman's body was found in Llano County, one of the areas inundated by the swollen Llano River, county officials said Wednesday. The woman's name has not been publicly released.On Tuesday, another body was found in the Colorado River in neighboring Burnet County, sheriff's office Capt. Tom Dillard said. Near-record flood levels swamped homes and caused a bridge to collapse.But there's a sliver of good news: While flood warnings are still in effect due to ongoing rain Wednesday, the Llano River's depth has dropped significantly."Right now, the Llano River is at about 12 ? feet, down from just shy of 40 feet yesterday," Llano County Emergency Management Coordinator Ron Anderson said Wednesday. 834

An online movement is raising awareness about the discrimination some high school students face at private and prep schools.One of many social media pages highlighting the issue is Black at Lovett. The organizers are two alumni who have taken submissions from students, parents and faculty, and share their experiences at the The Lovett School anonymously. Some of the stories go back decades.“I guess one of the things that was kind of surprising, but also we all knew what was going on, was that we all shared a lot of the same stories and a lot of the same experiences with the same students, the same administrators, the same teachers,” said Allison Burns, co-creator of Black at Lovett.The alumni have worked together using experiences from their current jobs to offer policy recommendations to Atlanta school and the community.“We want to make this better for future black students who attend this school, and that's the driving force behind this and why we want this to be an effort of love, a labor of love in some ways,” said Ashley Jeffrey, co-creator of Black at Lovett.Another page, True Colors of Columbia, highlights stories from Columbia Grammar & Preparatory School in New York. The co-creators just graduated and echo what they say needs to be done to help the next generation at these institutions.“How many more discussions with the administration, petitions, and emails and meetings do we need to have until kids aren't being told that they're going to be lynched?” asked Lauren Gloster, co-creator of True Colors of Columbia.While grateful for the education, the girls say they've felt the need to step in to help peers better understand racial differences. They're also worried current students might not speak up for fear of losing scholarships.“We all felt very compelled to not only create a safe platform where students like us could share their experiences and their stories but could also feel a sense of unity and community as well,” said Imani Camara, co-creator of True Colors of Columbia.We reached out to both schools.Lovett sent us a statement saying they don't want anyone to feel silenced due to their identity. They're taking part in the dialogue and will use recommendations from a committee for the upcoming school year. Read their statement below: 2299
