Seattle Seahawks head coach Pete Carroll said Tuesday he isn't sure if either safety Kam Chancellor or defensive end Cliff Avril will play football again after each suffered neck injuries in the 2017 season. "Cliff and Kam are going to have a hard time playing football again," he said, per Bob Condotta of the Seattle Times, adding that it would be each player's decision in regard to a potential return. It isn't the first time that Carroll has suggested Chancellor faces a major decision about his football future. "The future is really again up to Kam," he said in late November during an interview on 710 ESPN Seattle (h/t Brady Henderson of ESPN.com). "He does what he wants to do with that. He'll tell you what he wants to tell you about it."
