The Kansas City Chiefs have designated running back Jerick McKinnon for return from injured reserve, giving them depth and an offensive weapon for the Super Bowl against the San Francisco 49ers. McKinnon missed the entire postseason and the final few games of the regular season due to a groin injury, but his practice window is now open, making him eligible to play in Super Bowl LVIII. He has a history with the 49ers and has proven to be an important part of the Chiefs' passing attack.
