The San Francisco Giants will not have Angel Pagan for the playoffs.

Pagan has a bulging disk in his back and will undergo surgery Thursday in Los Angeles. The outfielder is expected to be out for three months.

"It's just time to get something done," Bruce Bochy said. "This thing's been nagging him for three or four months. It's just not getting any better. We want to get it done now so he'll be a full go in spring training."

Pagan hit .300/.342/.389 in 96 games this season.
