Querrey out at least 4-6 weeks

NEW YORK -- Sam Querrey cut his right forearm in a freak accident after practicing for the Thailand Open in Bangkok and will be out at least four to six weeks, the U.S. Tennis Association says.

USTA spokesman Tim Curry says the 21-year-old Querrey sat on a glass table after practice Monday and fell through, hurting his arm. The injury required emergency surgery.

A right-hander from Thousand Oaks, Calif., Querrey is No. 25 in the ATP rankings.

Querrey will be replaced by American Donald Young in the Thailand Open singles main draw.
