A commemorative plaque honoring Barry Bonds for his 756th home run has gone missing from San Francisco's AT&T Park.

Giants spokeswoman Staci Slaughter said the team is in the process of replacing the plaque, which hung on the brick facade inside the ballpark beneath the flag court area in right-center field until a few days ago.

"We're in the process of replacing it," Slaughter said. "We're not sure what happened. We're reviewing video, but haven't found anything yet."

There is still white glue on the brick wall where the plaque used to be.
