Rangers' Callahan suffers broken thumb

New York Rangers captain Ryan Callahan is expected to be sidelined three to four weeks after sustaining a broken thumb in Wednesday night's 2-0 victory over the Washington Capitals.

Callahan had returned to the lineup after offseason shoulder surgery and was off to a good start before the injury. He scored three goals in his past two games, including two on power plays Saturday against the St. Louis Blues. In Wednesday's game, he scored once and had six shots on goal.

Callahan joins a growing Rangers injury list that includes forward Rick Nash, who has missed three games after he took a hard hit last Tuesday in San Jose, and winger Carl Hagelin, who is on injured reserve after offseason shoulder surgery.

To replace Callahan on the roster, the Rangers recalled forward Darroll Powe from the Hartford Wolf Pack. Powe, acquired from Minnesota last year, has played in the Wolf Pack's four games this season and scored one goal. The 28-year-old also has NHL experience with the Philadelphia Flyers.
