Datsyuk suffered a groin injury in the morning skate and it will prevent him from playing Friday against the Devils, Ansar Khan of MLive.com reports. Datsyuk's injury wasn't reported earlier in the day as the team was likely waiting to see if he could go. It appears the injury is serious enough to keep him out Friday, and could leave his status for Sunday's game against the Lightning in question as well. The team should update his status in the next couple days, but he should be considered day-to-day unless something indicates otherwise.
