A hobbled LeBron James initially asked to check out of the game in overtime before quickly changing his mind and waving off his substitute.

He grimaced slightly after knocking down the go-ahead 3-pointer with under a minute left and was on all fours near midcourt after Shelvin Mack's potentially game-tying 3 clanked off the rim at the buzzer.

The battered and bruised Cleveland Cavaliers are a win away from the NBA Finals. A victory on Tuesday could give them some needed rest before then.

James had his first triple-double this postseason with 37 points, 18 rebounds and 13 assists and the Cavaliers defeated the Atlanta Hawks 114-111 on Sunday night to take a commanding 3-0 series lead in the Eastern Conference finals.

James, who missed his first 10 shots from the field, ended 14-of-37 from the field. His shot to give Cleveland a 112-111 advantage with 36.4 seconds left was his only 3 of the game.

Jeff Teague, who posted 30 points, seven assists and six rebounds, drove down the lane and had a step on James at the other end, but James altered the shot and Teague's layup was well off the mark.
