Hossa, 33, was injured during Game 3 of the Western Conference quarterfinals in April after an illegal hit by Phoenix Coyotes forward Raffi Torres, who was suspended for the hit to the head.
"Everything could be different when I'm on the ice, if I get hit or if someone pushes me," Hossa said at the Hawks convention in July. "But without contact, I'm doing everything on a high level."
If the NHL lockout drags on, it will give Hossa more time to recover.
In 81 games with the Hawks last season, Hossa recorded 29 goals and 48 assists for 77 points.
