Thunder center Steven Adams sidelined with concussion

LOS ANGELES -- Oklahoma City Thunder center Steven Adams will miss Monday's game against the Los Angeles Clippers with a concussion, the team said.

Adams is in the league's mandated concussion protocol; the timetable for his return is unknown.

Adams was injured early in the third quarter of Sunday's game against the Sacramento Kings after falling and hitting the back of his head on the floor. Adams immediately exited the game and did not return.

With Adams limited against the Kings, backup Enes Kanter scored 29 points and grabbed 12 rebounds in 32 minutes in the Thunder's 122-118 victory. The team has not yet announced who will start in place of Adams against the Clippers.

In 42 games this season, Adams is averaging 12.0 points and 7.5 rebounds in 29.9 minutes per game.
