The Toronto Maple Leafs confirmed that goaltender Petr Mrazek exited tonight’s game with a groin injury and would not return. It has been a tough stretch for the Maple Leafs in net, as well as a tough stretch for Mrazek himself, and this injury certainly does not help either.

It was early in the first period against the Boston Bruins that Mrazek appeared to come up limp. In pain, Mrazek tried to stretch, but was eventually pulled and replaced by rookie Erik Kallgren in net. While the Maple Leafs do expect Jack Campbell to return soon, an exact return date is unknown, and leaves Toronto without a true backup, certainly for tonight.

For Mrazek, a tough season gets tougher. After missing stretches early in the season with a groin issue, he appeared to be fully healthy and performing well before struggling greatly the past couple of months, eventually leading to being put on waivers on March 20th. After Mrazek cleared, he was re-called, he appeared to be refresh and back to his old ways, stopping 54 of 58 opportunities in two starts since returning, winning both.
