As the Edmonton Oilers prepare for a crucial Game 4 matchup against the Vegas Golden Knights on Monday night, concerns surrounding goaltender Calvin Pickard‘s health have intensified.

The Edmonton Oilers are gearing up for Game 3 of their second-round playoff matchup with the Vegas Golden Knights. Edmonton took the first two games of the series on the road and now holds a 2-0 series advantage as they head home for Games 3 and 4.

While the Oilers haven’t confirmed when the injury took place, Pickard appeared to be shaken up moments before the Golden Knights tied Thursday’s game 4-4 late in the third period. He was spotted lingering after having Tomas Hertl fall on his leg.
