Jochen Hecht was a surprise participant at the Sabres' morning skate Friday.
It was the first time he was with the team since suffering getting hurt in a game at Toronto on March 29. The Sabres list him as having an upper-body injury, but the Buffalo News is reporting Hecht has a concussion.
"Jochen feels good," Sabres coach Lindy Ruff said. "He's skating now, and hopefully next day or so he can get involved in full practices."
