Shoulder injury stops Haas again - could it be curtains for the German?

Another day, another injury withdrawal for Tommy Haas. According to FOXSports.com,

[He] withdrew [from the BMW Open] with a painful right shoulder. Haas said he would skip the upcoming tournaments in Hamburg and Rome.

So far the German withdrew from the Aussie Open, gave a walk-over to Roger Federer at Indian Wells, and retired from Monte Carlo and now Munich all because of his shaky shoulder.

I think the curtain is calling for the 30-year old.
