Trevor Ariza grimaced and flashed uncomfortable grins as he answered questions following the Wizards’ 101-97 victory over the Atlanta Hawks. On a night in which players were slipping and sliding all over a slick court, which was the result of condensation from a hockey game played earlier, Ariza took the nastiest spill and injured his left groin in the process. After moving gingerly through the locker room, Ariza said he wasn’t certain if he would be available on Monday when the Wizards take on the Charlotte Bobcats in a game that could provide more security for a Washington team that is hoping to avoid the seventh seed in the Eastern Conference playoffs. “I’m okay,” Ariza said after scoring 13 points in the win, then chuckled to himself. “We’ll see what happens.” With the Wizards leading 75-70 in the third quarter, Ariza was running back on defense when he hit the floor and started reaching for his groin. Martell Webster fouled Lou Williams to stop play and Ariza rolled around a few times in agony until head athletic trainer Eric Waters assisted him to the bench. Ariza didn’t immediately leave the game. He finished out the period, took a breather and returned to play the final five minutes. “I try to play the game as fast as I can all the time, but after I fell and slipped, I slowed down for sure,” Ariza said. “Somebody couldn’t really gotten hurt.”
