Marty Turco has cleared waivers and he practiced with his new Boston teammates for the first time on Wednesday. The 36-year-old Turco will backup the 37-year-old Tim Thomas for the Bruins until Tuukka Rask recovers from his lower abdomen/groin strain. Turco signed a one-year, $600,000 contract with the Bruins following word on Rask's injury. He will not be eligible to play in the playoffs.
