Chicago Bears starting center Lucas Patrick left practice Thursday with an apparent injury.
Patrick, who turns 29 on Saturday, walked off the field with trainers before taking a cart to the locker room.
He signed a two-year, $8 million contract with the Bears in March that includes $4 million guaranteed in 2022.
Patrick played his first five NFL seasons with the Green Bay Packers, starting 34 of 73 games from 2017-21.
