Forward Kyle Okposo left the team's win over Ottawa on Saturday with 10:35 remaining in the second period. The Sabres entered that game without a trio of forwards in Vladimir Sobotka (out four to six weeks), Marcus Johansson (out through the weekend), and Johan Larsson (day-to-day).

Thompson, 22, is tied for the team lead in Rochester with 12 points (6+6) in 16 games while his 67 shots on goal rank second in the AHL. He appeared in 65 games with Buffalo last season and then added roughly 10 pounds of muscle in the offseason, which translated during a strong preseason in which he scored two goals.

"I think my skating's gotten a lot better over the summer just because my leg strength I think's gotten a lot more powerful," Thompson said in a recent episode of Americans Made (below).

As the result of recent injuries, Thompson is the third player the Sabres have recalled in the past week. Curtis Lazar scored in his Sabres debut on Thursday, then center Rasmus Asplund filled in for Larsson to make his NHL debut Saturday, drawing high praise from coach Ralph Krueger.

"Outstanding, I mean, he was moving his feet all the time, both side of the puck, the penalty kill, he was creating offensive chances, he played without fear and showed a lot of courage," Krueger said of Asplund.

"It's what we saw in training camp. It was an exciting first game for anybody to come into the NHL and do what he did."
