BUFFALO, N.Y. -- Sabres left wing Thomas Vanek missed Buffalo's game against Pittsburgh on Saturday because of soreness in his stomach/abdominal region.
Sabres coach Lindy Ruff disclosed the injury at the team's morning skate, but didn't say how much time Vanek may miss. Vanek's problem stems from taking pucks to the midsection over the past week.
"He hasn't been himself the last couple of games," Ruff said.
Vanek scored his 10th goal of the season in the Sabres' 5-2 win over Toronto on Friday, tying him with Clarke MacArthur for the team lead.
The two-time 40-goal scorer missed two games earlier this season with an upper-body injury.
Tough guy Patrick Kaleta returned after missing Friday's game because of a head/neck injury sustained against Ottawa on Wednesday.
