Pavel Datsyuk (head) won't play Friday and it's unclear when he'll be able to return. He didn't skate on Thursday but he feels like he is making some progress. "Slowly, a little bit better," he said. "(But) I'm not feeling where I am supposed to be." Datsyuk has done some light skating, but since he's suffering from concussion symptoms he'll have to go through the protocols associated with the ailment before he's cleared to play again.
