Coach Lindy Ruff said before the game that Sekera will miss at least a few days and potentially longer.
Sekera was hurt Saturday, when he was struck in the leg by Canadiens defenceman Alexei Emelin's shot in the first period of a 6-1 loss at Montreal. He played a few more shifts before missing the final two periods.
The Sabres are already missing veteran defenceman Robyn Regehr (lower body), who will miss his fourth straight game. Ruff said Regehr is expected to return to practice this week.
That was something I've been dreaming of, something I've told myself before the third period I was going to do ... It was an amazing feeling. It's hard to describe. I didn't believe it went in at first but when I saw all the reaction and all the fans going crazy and my teammates going crazy, it's just an unbelievable feeling. I didn't know what to do. I didn't know whether to jump or just skate and do a Theo Fleury. I don't think I'm the same caliber player he is so I couldn't do it.
