Coach Jon Cooper suggested Tuesday that Killorn (undisclosed) is unlikely to return for the Lightning's remaining two games of the regular season. "I don't think it's anything that's going to keep him out of the first round," Cooper said. "But another week and a half and I'm hopeful he'll be back." Killorn wasn't a participant in Tuesday's practice and hasn't skated since suffering the injury during last Thursday's game against the Senators. While the Lightning would ideally like Killorn to log another regular-season appearance before throwing him back into the lineup during the playoffs, avoiding a potential aggravation of the injury is the team's primary objective.
