Johnson did not leave with the team Saturday night for Sunday's game at Cleveland after he suffered a strained right thumb in the Hawks' 98-87 win over the Nets.
Johnson was injured early in the third quarter of Saturday night's game when reaching for a loose ball. He says his hand hit Anthony Morrow's hand, bending his thumb back.
He was escorted to the locker room for X-rays before returning to the bench later in the quarter with ice on his hand.
He had 12 points when he was injured.
