The Ottawa Sun reported that Anderson will miss at least a week but should not need surgery.
Over 33 games this season, Anderson has gone 14-12-7 while posting a .925 save percentage.
From the Sun:
“It’s just the same thing,” Senators general manager Bryan Murray said. “He was not 100% when he came back to backup. He said he could handle the puck fine and we put him against (Calgary and Boston) but he didn’t still feel like he was where he should be.
“The other night, supposedly in the warm-up, he got hit in the same spot and it was bothersome. The thought was just get him out of the net, get him out of practice, do an MRI and all the evaluation again just to see what’s going on because it’s been (almost two months).”
Hammond has posted a 10-0-1 record since he made his first NHL start against the Montreal Canadiens.
