Hold your breath, Toronto. Maple Leafs savior Auston Matthews is set to undergo an MRI on Friday for what's believed to be an injured shoulder, according to TSN's Bob McKenzie.

Matthews was hurt late in the third period Thursday during Toronto's game against the Islanders after colliding with New York forward Cal Clutterbuck. He went to the locker room and didn't return.

An injury of any severity could be a massive blow to a Maple Leafs club sitting pretty in the Atlantic Division standings, as Matthews is once again leading his club in goals and points with 28 and 50, respectively.
