Concerning update on Auston Matthews on Monday morning.

The Toronto Maple Leafs may have a big problem on their hands.

In Game 4 of their opening round Stanley Cup playoff series against the Boston Bruins, star forward Auston Matthews was pulled from the game by the team's medical staff. Matthews has reportedly been dealing with some kind of illness, speculation suggests it may be food poisoning of some kind, and it became severe enough during the course of the game that he was unable to continue.

The big question now of course is whether or not Matthews will be healthy enough to play in Game 5, where the Maple Leafs will be facing elimination down 3-1 in this series already.

The first update we have in that regard is a concerning one, with Matthews notably absent from the team's morning skate on Monday.

The big concern is of course that Matthews may be too unhealthy to participate, but it is still too quick to rush to judgement. It could very well be that, due to his illness, the Maple Leafs feel that an extra day of rest may be more valuable right now.

What I do know for certain is that Max Domi was centering the Matthews line in practice on Monday, which could be a preview of what we might get on Tuesday if Matthews is indeed held out of Game 5.

Here is how the forward line looked on Monday:

Bertuzzi — Domi — Marner
Knies — Tavares — Nylander
Robertson — Holmberg — Järnkrok
Dewar — Kämpf — Reaves
