Golden State forward Matt Barnes has a sprained finger on his shooting hand, adding another injury to the winless Warriors' early woes.

Barnes, a key part of the Warriors' postseason run last spring, was injured in the Warriors' loss to Cleveland on Tuesday night, coach Don Nelson said.

Barnes, who missed Wednesday's practice, dislocated the knuckle on the ring finger of his right hand. The injury could sideline him when Golden State hosts Dallas on Thursday night in a rematch of last season's playoff shocker, when the Warriors became the first No. 8 seed to beat a No. 1 seed.

"I don't know how he could possibly catch a ball," Nelson said. "He played through it, but it's all swollen and discolored now."
