Ten months have passed since right wing Ryan Callahan planted himself in front of Boston defenseman Zdeno Chara, whose slap shot has been timed at well over 100 miles per hour, and tried to help the Rangers sit on a late lead by taking one for the team.

Callahan blocked the shot, and the Rangers won the game and made the playoffs. But Callahan was not available to play in them because Chara’s shot broke Callahan’s right ankle.

Callahan, now the Rangers’ captain, is no more cautious than he was before the injury. Heading into the Rangers’ game Tuesday against Chara’s Bruins in Boston, Callahan is fourth among N.H.L. forwards this season in blocked shots, with 60 in 54 games. Two of his teammates, defensemen Dan Girardi and Ryan McDonagh, are among the top five over all, each with more than 130 blocks.

“We don’t want anybody getting injured, but things happen,” Callahan said after a recent practice. “There are going to be guys getting hit and being injured, guys blocking shots and being injured. It’s a physical game, and things happen, but that’s not something you can worry about. We’ve got to keep blocking shots. We can’t let those shots go through.”
