Matheson exited Friday's practice session early with a lower-body injury. Coach Mike Sullivan told reporters, "He's being evaluated for just a nagging lower-body thing. We don't think it's serious," per Pens Inside Scoop.

EDGE Analysis

The fact that the Penguins moved forward with placing Juuso Riikola on waivers for the purpose of reassignment to the minors should be an indication they expect Matheson to be fully fit in time for Opening Night against the Lightning on Tuesday. Still, it's a situation worth monitoring for fantasy players, especially considering Matheson should be in the mix to quarterback the No. 2 power-play unit this season.

EDGE Analysis

After Matheson was injured, he was initially labeled week-to-week but with the Penguins not expected to play for the next few days until the postseason begins, the blueliner could be an option in the playoffs. Whenever he is cleared to play, Matheson should immediately jump back into the lineup, which will relegate Chad Ruhwedel to a spot on the bench.

EDGE Analysis

With just four games remaining, Matheson will be sidelined for the rest of the regular season and could be unavailable for the start of the playoffs as well. The 27-year-old blueliner has registered just one point in his last six contests but has been critical to the club's pursuit of an East Division title. With Matheson shelved, Mark Friedman figures to jump into the lineup while John Marino and Marcus Pettersson should see significant upticks in ice time.

EDGE Analysis

Matheson has put together an impressive four-game point streak (two goals, four assists). The hot streak probably won't last much longer considering he had only five points in his first 27 games with the Penguins, but Matheson could be worth a look in the short term while he's rolling.

Matheson scored the game-winning goal Thursday in a 4-1 victory over the Penguins.

EDGE Analysis

It was a pretty end-to-end rush for the defender. He roared down the right side, burst past the defender while protecting the puck and drove hard at Dan Vladar. Matheson slid the puck wide and around the sprawling netminder, and pushed it home. It was a Sports Center moment for sure. Matheson has gotten warm of late -- he has four points in his last five games.
