Kemba Walker was carried off the court on a stretcher in Friday’s game against the Nuggets. The Celtics Guard was chasing a loose ball when he ran headfirst into his teammate Semi Ojeleye and collapsed.

Yahoo Sports reported that Walker was suffering “concussion-like symptoms” after being hospitalized which indicates something less serious than what looked like it would be a serious neck injury.

Walker was cleared on Saturday to rejoin the team in Monday’s game against the Sacramento Kings at home.

Walker only played 12 minutes at the Pepsi Center in Denver and finished with zero points and 3 assists. in the 92-96 loss.
