Matthews was placed on injured reserve Sunday, James Mirtle of The Athletic Canada reports.

EDGE Analysis

With Matthews already expected to be out at least a week, the transaction won't effect his return timetable in any way, and he should be eligible to be taken off injured reserve as soon as March 1. The move was likely made to free up a roster spot for newly acquired Tomas Plekanec, and William Nylander should continue to center the first line in Matthews' absence.

Matthews (shoulder) is estimated to be out 7-to-10 days, the Toronto Sun reports.

EDGE Analysis

Coach Mike Babcock reportedly applied a "day-to-day" label for Matthews' injury Friday, but this report clarifies that he actually means the star pivot could be out for a week at a minimum. "He's going to be out for a bit anyway, so it's an opportunity to see Willy (Nylander) or (Patrick) Marleau or whoever will play in the middle or someone else," Babcock said. "We have guys on the (AHL) Marlies dying for an opportunity, too. We'll sort it out as we go." Matthews' MRI from Friday evidently is still pending, but the eventual results should help firm up the return timetable for the American star.

Matthews (upper body) underwent an MRI on Friday to confirm his shoulder injury isn't serious, reports https://twitter.com/RealKyper/status/967107207266410496">Nick Kypreos of Sportsnet.ca.

EDGE Analysis

Results have not been released and won't be, given the Leafs history of locking down injury information. There has been talk that Matthews injury is similar to the one Mitch Marner suffered earlier this season. Marner missed just five games. Matthews is officially out of the lineup for Saturday's game, but if the injury is like Marner's, he could be back by March 10 against the Penguins.

Matthews (shoulder) will not play Saturday night against the Bruins, Joe McDonald of BostonSportsJournal.com reports, citing Maple Leafs coach Mike Babcock.

EDGE Analysis

This was expected to be the case, as Matthews sustained an apparent right shoulder injury in Thursday's 4-3 win over the Islanders. By sitting this one out, the offensive wunderkind should be afforded two full days of rest before the Maple Leafs go all out in preparing for Monday's battle with Tampa Bay.

Per head coach Mike Babcock, Matthews (shoulder) is day-to-day and will be out "for a bit", David Alter of The Canadian Press reports.

EDGE Analysis

More information on Matthews status is expected to be available Saturday, but the day-to-day designation signals that it's nothing serious. Nevertheless, the Maple Leafs won't rush Matthews back, since they have a 16-point playoff cushion and need him fresh for a Stanley Cup run. In the meantime, William Nylander will center Toronto's top line.

Matthews (shoulder) was not on the ice for practice Friday morning, Dave McCarthy of NHL.com reports.

EDGE Analysis

According to TSN's Bob McKenzie, the phenom is scheduled to undergo an MRI to determine the severity of his apparent shoulder injury. Given Matthews' high profile, we anticipate clarity on this situation well ahead of Saturday's home clash with the Bruins.

Matthews exited Thursday's 4-3 win over the Islanders in the third period with an apparent right-shoulder injury, Damien Cox of the Toronto Star reports.

EDGE Analysis

Matthews suffered the injury when he was crunched between New York's Adam Pelech and Cal Clutterbuck on his way to the Islanders' net. The 20-year-old pivot briefly spoke to Toronto's trainers on the bench before heading down the tunnel and into the locker room. Matthews wasn't able to return for the games' overtime period, and coach Mike Babcock didn't have an update on his status during his post-game press conference, Terry Koshan of the Toronto Sun reports. The severity of Matthews' injury remains unknown, but the Maple Leafs should release an update on his condition after he undergoes further evaluation Friday morning.

Matthews scored the game-winning goal in Sunday's 3-2 victory over the Red Wings.

EDGE Analysis

Matthews is now a top-10 goal scorer overall. Pretty good for a guy who missed several games to injury. Play him and forget about him. He's almost a point-per-game stud at just 20 years of age.

Matthews recorded three assists through 16:48 of ice time during Monday's 4-3 win over Tampa Bay.

EDGE Analysis

The sophomore now has 26 goals, 21 assists and a high-end 3.2 points per 60 minutes through 48 games this season. Fantasy owners would love to see Matthews receive a few more minutes, as his ice time trails most star players. Still, it's difficult to nitpick considering his high level of production. It's also worth noting that he's heating up when it matters most with seven goals and seven assists through his past 11 contests.

Matthews scored twice, added an assist and registered a plus-5 rating during Monday's 7-4 win over Anaheim.

EDGE Analysis

Matthews has now collected 12 goals and 17 points through 19 games since returning from concussion-like symptoms Dec. 23. He's locked in as a go-to fantasy asset in all settings, but it's worth noting that his ice time trails most superstars, so his upside is slightly capped. Still, there's potential for a late-season surge here, and this time of year is when it matters most.
