Hossa has shoulder surgery
"Marian's surgery today went as well as we had hoped, and he is right on track for the anticipated recovery we had planned on, which is approximately four months," Dr. Michael Terry, the Blackhawks' team physician, said.
Hossa is expected to miss the first two months of the regular season.
The Blackhawks signed Hossa to a 12-year, $62.8 million on July 1. The team said it knew about the injury before signing Hossa, who led the Detroit Red Wings with 40 goals last season.
