ARLINGTON, VA — The Capitals announced Thursday that former NHL player Zenon Konopka has joined their coaching staff on a temporary basis this week. Konopka and Capitals skills coach Kenny McCudden led a session for the team’s non-game group on Thursday morning, with Konopka coaching players on faceoffs for part of the skate. “So, brought him in for the next three days.”Over parts of nine seasons in the NHL, Konopka played 346 games for seven teams. Since retiring from professional hockey, Konopka has dipped his toe into coaching in recent years. The Capitals are still without assistant coach Mitch Love, who is on team-imposed leave pending the results of an NHL investigation.
