The Buffalo Sabres recalled goaltender Robin Lehner on Thursday from his conditioning assignment with Rochester of the American Hockey League.

Lehner went 1-2-0 with a 3.36 goals-against average and .888 save percentage in three AHL starts as he works his way back from a high-ankle sprain sustained in the Sabres' season opener Oct. 8 against the Ottawa Senators.

Lehner was acquired from the Senators during the offseason to be the Sabres' No. 1 goaltender. Ottawa selected him in the second round (No. 46) of the 2009 NHL Draft and he went 30-36-0 in 86 games over parts of five seasons with the Senators.

The Sabres, who host the Boston Bruins on Friday, reassigned goalie Linus Ullmark to Rochester. Ullmark made his NHL debut this season and was 7-10-2 with a 2.58 goals-against average and .915 save percentage in 19 games.
