The right wing was hurt in the second period of the Blackhawks'
4-3 overtime win at Ottawa on Saturday. He did not play in
Chicago's 3-2 home victory over Edmonton on Sunday.
Havlat missed 22 games earlier this season after injuring a
shoulder in the Blackhawks' season opener at Minnesota. In 12 games
this season, he has five goals and six assists.
The 26-year-old has never played an entire 82-game NHL schedule
during seven seasons with Ottawa and Chicago.
Last season, his first with the Blackhawks, Havlat was limited
to 56 games due to ankle, groin and shoulder injuries.
While with the Senators in 2005-06, Havlat played in 18
regular-season games due to shoulder surgery. In the playoffs,
however, he had seven goals and six assists in 10 games.
