Dodgers first baseman Adrian Gonzalez was a late scratch for Friday's series opener at San Francisco with neck pain.

Manager Don Mattingly said Gonzalez suffered the injury in a collision with an umpire in Wednesday's 7-3 loss to Colorado.

Gonzalez told Mattingly just before the team took batting practice Friday that, "I've got a little something going on my neck, I feel like I've got a knot in there."

Mattingly said he believes the injury is day-to-day, and said Gonzalez would be available as an emergency replacement Friday.

The injury was nevertheless a big blow to the Dodgers' sputtering offense facing a left-handed pitcher, Barry Zito, who has given them problems in recent years.

Gonzalez is batting .381 (16 for 42) with a .904 OPS against left-handed pitchers.

The Gonzalez injury is the latest setback to a team that has been hit hard by injuries in recent weeks. Earlier in the day the Dodgers put starting pitcher Ted Lilly (back) on the disabled list for a second time this season - the club's ninth injured-list entry this season.
