Mitchell underwent an MRI on his left foot, which came back negative according to ESPN's Chris Haynes, meaning he will be available for Game 2.
Mitchell returned with 7:47 left in the fourth quarter but was subbed out about a minute later after making a jumper and grimacing as he ran back on defense. However, the former Louisville standout did suffer an injury during Game 1 that forced him to the sideline, albeit briefly.
He finished with 27 points and 10 rebounds in Oklahoma City's 116-108 victory. However, it was clear that he was still a bit shaken up and head coach Quin Snyder made a decision to pull him from the game once again.
Jazz coach Quin Snyder said all signs point to Mitchell being ready for Game 2 on Wednesday.
It was his first playoff game with the Thunder since being acquired in a trade with the in in the offseason.
