Livings had arthroscopic surgery on his right knee in the offseason but had not missed any workouts. He was bothered for much of last year by the injury but started every game.
A source close to Livings said he was fine.
Livings’ absence meant the Cowboys were without their two starters. Mackenzy Bernadeau is rehabilitating from offseason shoulder surgery. Bernadeau, who missed all of last year’s offseason because of hip surgery and part of training camp because of knee surgery, could return for the June 11-13 minicamp. He is working through individual drills but has not worked in 11-on-11 drills.
