In making the announcement late Friday afternoon, the team said James will be a “game-time” decision when the Heat are host to the Chicago Bulls Sunday.
James was hit accidentally by the Thunder’s Serge Ibaka with under six minutes remaining the game and the Heat holding a 16-point lead.
The blow bloodied James’ nose, knocked him to the floor and sent him to the locker room -- but went unnoticed by the officials. James still converted a slam dunk on the play, giving the Heat a 90-74 advantage.
It gave him 33 points for the game, his fourth straight outing with at least 30 points since being held to 13 points, matching a season low, in a loss at Utah on Feb. 8.
The Heat went on to a 103-81 victory to gain a split of the two-game season series. The Thunder won 114-95 in late January.
If he doesn’t sit out the game against the Bulls, James could be wearing a protective mask for the second time in his career. He also wore one in 2005 while with the Cleveland Cavaliers.
The Heat and Bulls will tip off at 3 p.m. ET Sunday at Miami’s American Airlines Arena. ABC will telecast the game.
