Matthews is dealing with an illness in addition to his undisclosed injury, making him questionable for Saturday's game in Boston, Terry Koshan of The Toronto Sun reports.

EDGE Analysis

Matthews woke up sick Thursday, which contributed to the decision to keep him out of a second straight game. If he can't play Saturday either, Bobby McMann will likely continue to hold down a bottom-six spot in the lineup.

EDGE Analysis

Matthews continues to deal with a lingering undisclosed injury that could sideline him for a second consecutive contest. While there is no replacing a world-class talent like Matthews, the task will fall to John Tavares, who moves into the first-line role. For his part, Matthews hasn't produced at the same level that saw him lead the league in goals last year, recording 20 goals through the opening 41 contests which is only good enough for 19th in the NHL.

Matthews is dealing with an undisclosed injury that will sideline him against the Predators on Wednesday, David Alter of Sports Illustrated reports.

EDGE Analysis

Matthews missed Tuesday's practice for a maintenance day and did take part in Wednesday's optional game-day skate, so his absence is not expected to be long-term. Still, losing a world-class center for any stretch of time won't help the Leafs' offense. Without Matthews, John Tavares' line will become the first unit while William Nylander will move to center on the second line. With a back-to-back on the schedule, Matthews could be in danger of missing out versus the Red Wings on Thursday as well.

EDGE Analysis

He was also one of two Leafs to beat Jordan Binnington in the shootout, only for the Blues to get three pucks past Ilya Samsonov in four rounds.

Matthews provided a goal and an assist in Toronto's 6-2 win against Colorado on Saturday.

EDGE Analysis

Matthews' helper came on a Toronto power play. He's up to 18 goals and 42 points in 37 contests this season, including 14 points with the man advantage. Matthews has been a steady contributor all season with his longest scoring drought being a two-game slump from Nov. 23-25.

Matthews scored a goal and added an assist in a 5-2 loss to the Capitals on Saturday.

EDGE Analysis

He wired four shots and laid two hits, too. Matthews' scoring streak had been snapped at eight games Thursday night against the Rangers. But he still has 16 points (seven goals, nine assists) in his last 10 games. Interestingly, Matthews only has one power-play point in this span, so he has been doing it the hard way.

Matthews had a goal and two assists in a 5-4 overtime win over Calgary on Saturday.

EDGE Analysis

Matthews scored the opening goal at 5:04 of the first on a power play -- he went glove side from the slot and the puck was off his stick in a remarkable 0.4 seconds. Yes, that fast. Matthews has a goal in four straight games and points in seven (six goals, seven assists). Last year's Rocket Richard winner is starting to gain a lot of momentum on the score sheet and has 15 goals and 34 points in 29 games so far.
