Tuukka Rask has signed a professional tryout contract with the AHL Providence Bruins, the first major step in the star goaltender's comeback with the Boston Bruins.

Rask, 34, is an unrestricted free agent who underwent surgery to repair a torn labrum in his right hip in late July. He is expected to start for Providence on Friday at home against the Lehigh Valley Phantoms. After his minor league conditioning stint, Rask is expected to sign a contract with Boston for his 15th NHL season.
