O'Reilly missed Monday's practice and is considered questionable for Tuesday's game against the Devils, Mike Morreale of NHL.com reports.

EDGE Analysis

There's no indication that O'Reilly suffered an injury in Saturday's game against the Rangers, but he did see a slight drop in ice time from his average. His absence could have big implications on the fantasy playoffs, so owners should check back for an updated status on game day.

O'Reilly lit the lamp twice on three shots in Saturday's 4-3 win over the Rangers.

EDGE Analysis

O'Reilly has found twine in two of the last three, which sounds like the center has been hungry around the crease, but that wasn't the case before his short spurt of markers. The 25-year-old went 24 straight without a goal, however he did notch 18 assists in that span. O'Reilly has reached 20 tallies for the second time in his career, although the minus-16 rating is one stat owners could do without.

O'Reilly recorded a shorthanded goal and added an assist in Tuesday's 5-4 loss to the Penguins.

EDGE Analysis

The 25-year-old has had a successful first season in Buffalo, racking up 57 points thus far -- his highest total since recording 64 with Colorado during the 2013-14 season. O'Reilly has points in two straight games and five points over his last six games. He continues to make for a strong play on a young, but talented Sabres team.

O'Reilly contributed an assist in Monday's loss to the Red Wings.

EDGE Analysis

O'Reilly helped setup a goal with just under two minutes remaining as part of a late flurry of goals, but Buffalo's comeback effort fell just short in the 3-2 defeat. The 25-year-old is amidst a long scoring drought, as he hasn't found the back of the net since Jan. 8, but he's continued to dish out the helpers during that span.

O'Reilly registered an assist and played 22:02 in his first game back from a foot injury on Wednesday.

EDGE Analysis

Despite head coach Dan Bylsma's promise that he won't be giving O'Reilly his regular minutes after an 11-game absence, O'Reilly ended up playing more than his season average. That's most likely because O'Reilly played 5:26 on the power play in a game filled with penalties, but with an assist and three shots on goal, O'Reilly didn't look very rusty. Though Jack Eichel is the team's franchise player, O'Reilly remains the team's No. 1 center and his 50 points, 20 of which come on the power play, make him a serviceable fantasy player.

O'Reilly (foot) will return to the lineup against the Canadiens on Wednesday, reports The Buffalo News.

EDGE Analysis

O'Reilly missed four weeks with a foot injury and will skate on a line with Evander Kane and Nicolas Deslauriers. Kane and O'Reilly showed some good chemistry early in the season, and although Kane has played well with Jack Eichel and Sam Reinhart, head coach Dan Bylsma is hoping to have two balanced scoring lines. The Habs should be a prime opportunity for the Sabres to score a few goals, especially with the Habs missing Carey Price and P.K. Subban.

O'Reilly (foot) was not wearing a red jersey at Monday's practice, reports Mike Harrington of The Buffalo News.

EDGE Analysis

This indicates that O'Reilly has been cleared for full contact after missing the past month with a foot injury. His official return date has not been set, and the Sabres have yet to officially activate him from the injured reserve, but will likely do so soon. The Sabres don't play until Wednesday against Montreal.

O'Reilly (foot) skated for over an hour for the first time since his injury, reports the Olean Times Herald.

EDGE Analysis

There is still no date set for O'Reilly's return, but the Sabres are hoping he can resume full practices next week. The Sabres' top center has not played since Feb. 18 and hopes to return by the end of the season. Jack Eichel has taken over as the team's No. 1 center in the meantime.

A lower-body injury is in line to keep O'Reilly out of action for three-to-four weeks.

EDGE Analysis

Coach Dan Bylsma delivered the news Sunday, which is a big blow to the Sabres' attack, with O'Reilly leading the team in scoring with 49 points in 59 games. Per the Buffalo News, O'Reilly suffered a foot injury Friday against Columbus, though the specific nature of the forward's injury has yet to be officially confirmed by the team.

O'Reilly will sit out Sunday's game against the Penguins with a lower-body injury.

EDGE Analysis

O'Reilly missed Saturday's game as well, so Sunday will mark a second straight absence for the 25-year-old despite optimism from coach Dan Bylsma that he'd be available. The Sabres don't play again till Wednesday against the Ducks, so O'Reilly should have another three days off to get back to full health.
