PHILADELPHIA -- David Krejci will miss the rest of the season after suffering a dislocated right wrist in last night's first period.

"Brutal," a source close to Krejci noted of the news.

Krejci was injured when he was blasted in open ice by Mike Richards, seconds before Miroslav Satan gave the Bruins a 2-1 lead. Krejci has four goals and four assists through nine playoff games, third-most behind Satan and Patrice Bergeron.

Krejci underwent surgery last night at Baltimore's Union Memorial Hospital. Dr. Thomas Graham, surgeon-in-chief, performed the procedure. Krejci is expected to return for the 2010-11 preseason, part of which the Bruins will spend in his native Czech Republic.

Krejci had been centering Satan and Milan Lucic on the team's most dangerous offensive line. Krejci was also the quarterback on the No. 1 power-play unit on the left-side half-boards, while also seeing plenty of penalty-killing time.

Krejci is the second top-six forward to be knocked out of the playoffs during the second round. Marco Sturm tore the ACL and MCL in his right knee in Game 1.

Either Trent Whitfield or Brad Marchand, who have been healthy scratches throughout the playoffs, will replace Krejci.

Comcast Sportsnet Philadelphia first reported the injury last night.

Corrected from broken wrist to dislocation.
