The Toronto Maple Leafs have a couple of uncertainties on their blueline heading into the playoffs, as head coach Craig Berube announced that defensemen Jake McCabe and Oliver Ekman-Larsson are dealing with upper-body injuries and are uncertain for Game 1 of the first round of the Stanley Cup Playoffs.

Both defenseman have been skating for the past couple of games, and are out on a day-to-day basis, but Berube wasn’t ready to nail down a specific time when they expect to be back, including Game 1 of their upcoming playoff series.

McCabe has missed the last five games after sustaining his upper-body injury late in the Leafs’ 3-2 win over the Florida Panthers on April 2nd. The Leafs have gone 4-1-0 in his absence.

McCabe has continued to produce at an increased level since joining the Maple Leafs, as his two full seasons with the Leafs thus far have seen his best results, including the 2 goals and 21 assists for 23 points in 66 games that he’s gotten this season.

Ekman-Larsson has missed the last two games with his upper-body injury. He was a late admission from Saturday’s lineup against the Montreal Canadiens, forcing the Leafs to play with only five defensemen in the game. They went on to win the game 1-0 in overtime, as well as winning the other game Ekman-Larsson has missed with their 4-1 win over the Carolina Hurricanes.

Ekman-Larsson is far from the elite defenseman that he was in his prime, but he’s still produced at a solid rate for a fourth/fifth defenseman on the team, with 4 goals and 25 assists for 29 points in 77 games.

With both defensemen out of the lineup, Phillipe Myers and Dakota Mermis are expected to continue to replace them for the time being.

The Leafs currently sit in first in the Atlantic Division with a 50-26-4 record. They’ll have the opportunity to clinch the division on Tuesday either with a point in their game against the Buffalo Sabres or with a Tampa Bay Lightning loss of any fashion against the Panthers.
