Tomas Vokoun was on the ice for 20 minutes Tuesday morning ahead of the team’s scheduled practice, marking the first time the veteran netminder has skated at KCI since aggravating his groin muscle strain on March 29 in Boston.

The 35-year-old Czech did extensive stretching and then tested his injured groin with hard stops and starts, as well as sliding motions across the crease. At one point, Vokoun skated over to the bench to consult with athletic trainer Ben Reisz and shook his head in apparent disapproval of how he responded to the exercise.

Vokoun is 25-17-2 this season with a .917 save percentage and 2.51 goals-against average but at this point there remains no timetable for his return. General Manager George McPhee didn’t offer any details about when the Capitals might expect the goaltender back, only to say Vokoun’s recovery is behind Michal Neuvirth’s.
