Marty Havlat is all too familiar with the rehab process required after shoulder surgery.

Four times in his decade-long NHL career, shoulder problems have forced Havlat to go under the blade, although he said the latest procedure in May was his first on the left side. Still, he doesn't see himself as particularly susceptible or cursed.

"It's an impact sport," Havlat, 30, said after practice Tuesday. "You get hit, they have boards and sometimes you fall awkwardly. Every time it's different stuff."

Havlat suffered a partial tear in his labrum last May while representing the Czech Republic in the world championships, something the Sharks were aware of last July when they acquired him from the Minnesota Wild in a trade for Dany Heatley. Havlat sat out the 6-3 victory over the Phoenix Coyotes that opened San Jose's season Saturday night, and he remains a question mark for Friday when the team returns to action in Anaheim.

But if others are getting antsy for an appearance by the high-scoring right wing who is penciled in on a line with Ryane Clowe and Logan Couture, Havlat is a model of patience because he knows how long it takes these things to heal.

"Four to six months, the rehab. We're doing pretty good," he said while acknowledging the situation is frustrating.

Though Havlat indicated it isn't something he thinks about, his experience with the Chicago Blackhawks at the start of the 2007-08 season has to reside in his subconscious at the very least.
