"He's fine," Zito wrote in an email. "Just a little tweak and he didn't want to push it. Probably play Friday."
Rask, 25, joined the Czech League's club in Plzen early in the NHL lockout (now in its 39th day) and on Tuesday, according to reports out of the Czech Republic, pulled himself out of a game after the first period. One report noted that he had a groin injury.
Rask sustained a serious groin injury March 3 against the Islanders, ending his 2011-'12 season and sending the Bruins into a mad scramble to find relief in net for top 'tender Tim Thomas.
After prolonged rest and physical therapy, Rask over the summer reported that he was back at full strength and signed a one-year contract extension. Once the NHL gets back in business (still waiting), Rask projects as the club's No. 1 goaltender, backed by Anton Khudobin.
Thomas, with one year left on his contract, told the Bruins over the summer that he likely won't play the upcoming season and possibly will retire.
