Stewart suffered the injury in his second game with the team, which came on March 6 against the Tampa Bay Lightning. While on a potential break away, Stewart collided with Lightning goalie Anders Lindback who was darting out of his net, and injured his right ankle.
Stewart had been acquired by the Sabres from the St. Louis Blues the week before on Feb. 28 along with goaltender Jaroslav Halak (since traded to Washington) in the trade that sent Captain Steve Ott and goaltender Ryan Miller to the Blues.
Prior to the trade, Stewart was in his fourth season with the Blues, and had 15 goals and 11 assists for 26 points in 58 games with the team this season. He also had 112 penalty minutes and a plus-2 rating in those 58 games.
Drafted 18th overall by the Colorado Avalanche in first round of the 2006 NHL draft, Stewart joined the Blues in 2011 as part of a multi-player trade with the Avalanche. Stewart then played 211 games with the Blues before being acquired by the Sabres, scoring 63 goals and adding 52 assists for 115 total points, to go along with 276 penalty minutes and a plus-7 rating. In 166 games with the Avalanche before the trade between 2008 and 2011, Stewart had 52 goals and 61 assists for 113 points, while also tallying 165 penalty minutes and a minus-24 rating.
Stewart has one year remaining on his contract, and will look to continue his time with the Sabres next season.
