Madison Bumgarner a late scratch with flu symptoms

SAN FRANCISCO -- San Francisco Giants ace Madison Bumgarner was a late scratch for Thursday night's game against the St. Louis Cardinals as a result of flu symptoms, the team announced.

Right-hander Matt Cain (3-10, 5.75 ERA) will start in his place. The team has not yet announced when Bumgarner will return to the starting rotation.

Bumgarner (3-6, 2.85) is 3-3 in nine starts since coming off the disabled list July 15 after spending nearly three months on it with a left shoulder AC sprain and bruised ribs. The 28-year-old left-hander suffered the injuries in a dirt-biking accident in Colorado on April 20.
