Robby Ginepri underwent surgery last week after breaking his arm in a biking accident.
"Ginepri was riding near his hometown in Kennesaw, Georgia, when a squirrel ran into his path," said the ATP website. "The American fell off his bike as he swerved to avoid running over the squirrel and rolled about 50 yards, breaking his left elbow at the ulna bone."
Ginepri will not play again this year but plans to return at the beginning of next season.
