It just wouldn't be the Stanley Cup Playoffs without a goalie controversy, now would it?

Marc-Andre Fleury had been a brick wall in the Penguins' crease so far in the postseason, but played like a giant block of Swiss cheese on Wednesday night. He got yanked after allowing four goals on nine shots.

Matt Murray, who missed the start of the playoffs due to injury, stepped in and allowed just one goal on 20 shots in his 2017 postseason debut.

When asked which goaltender will start in Game 4, head coach Mike Sullivan said "We'll sleep on it," according to Sportsnet's Chris Johnston.

Sullivan also added that he "hasn't given any consideration" to such decision as of yet, per Sam Werner of the Pittsburgh Post-Gazette.

It's certainly a tough decision for Sullivan to make. Fleury is an experienced veteran who got the team through the playoffs' first two rounds with his superb play. On the other hand, Murray was Pittsburgh's better goalie throughout the regular season, showed no signs of rust in his Game 3 relief outing, and his play during last year's Stanley Cup run provides evidence of big-game composure.

It could be one restless sleep for Sullivan.
