According to Anthony Slater, Steven Adams could not finish Thursday's game against the Chicago Bulls due to soreness in his back. Adams left the Bulls game with 3:20 to go in the third quarter, and did not appear to be in any visible pain. Back soreness has been an issue for Adams this season. Back on October 7th, Adams sat out the Thunder's pre-season opener against the Minnesota Timberwolves.
Currently, Adams is averaging six points and six rebounds in 26 minutes a game. We won't know whether Adams will miss any time until tomorrow's practice.
