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

An auction house in New Jersey is offering bidders the chance to blow up an Atlantic City casino and hotel once owned by President Donald Trump.Bodnar's Auction Sales says it will open auction bidding Saturday for the chance to press the button that will ignite the controlled implosion of the Trump Plaza Casino and Hotel.According to a description on the live bidding website, all proceeds from the auction will "benefit" the Boys & Girls Club of Atlantic City."Ever since the start of this pandemic they have seen an increase of young children and adolescents benefit from the services of The Boys & Girl Club and are in need of all the assistance they can get for the community," Bodnar's said in its item description.Bidding for the chance to implode the building is open to anyone, and Bodnar's adds that the demolition can be conducted "anywhere in the world as well as close to the Plaza as we can safely get you there."Trump Plaza Hotel and Casino opened in 1984 — Trump's first property on the famed Atlantic City Boardwalk. However, the casino closed in 2014 and has sat abandoned ever since.In June, Carl Icahn — the senior lender for the Trump Plaza's mortgage — submitted plans to Atlantic for the casino's planned demolition. The city asked that the building be demolished because it had fallen into disrepair, and debris was falling to the boardwalk below.The implosion of the casino is currently slated for early February, according to CNN. Bidding in the auction is slated to open at 7 p.m. ET on January 19. Click here to participate. 1569

An eruption from the Kilauea volcano's summit shot ash and smoke into the air early Thursday on Hawaii's Big Island, and the resulting plume is expected to cover the surrounding area, according to the Hawaiian Volcano Observatory.Nearby residents are being asked to shelter in place if they are in the path of the ash plume, which the wind is carrying to the southeast of the volcano."Driving conditions may be dangerous so if you are driving pull off the road and wait until visibility improves," an alert from the observatory warned.Thursday's eruption is just the latest volcanic activity contributing to the nightmare on the Big Island since the volcano first went off May 3.An ash plume Wednesday rose roughly 12,000 feet into the air, and on Tuesday, the US Geological Survey issued a red alert, which means a major eruption is imminent or underway and ash could affect air traffic.It is not clear if this was a phreatic eruption, which US Geological Survey officials have been saying is capable of sending ash plumes as far as 12 miles away from the summit.These are steam-driven explosions that occur when water beneath the ground or on the surface is heated by magma, lava, hot rocks or new volcanic deposits, the USGS says. The intense heat may cause that water to boil and result in eruptions.The lava lake in the crater has been dropping since May 2, which increases the chances for a phreatic explosion, but it will be difficult to warn residents who may be in the path of such an eruption.Phreatic eruptions are "notoriously hard to forecast, and can occur with little or no warning," Hawaiian Volcano Observatory geologist Janet Babb said.While the ash being launched into the sky is not poisonous, Hawaii County officials have warned residents about toxic sulfur dioxide seeping out of 21 fissures caused by the volcano."Severe conditions may exist such as choking and inability to breathe," the county's Civil Defense Agency said Wednesday. "This is a serious situation that affects the entire exposed population."The-CNN-Wire 2051
