Per the San Jose Mercury News:

A warrant for the arrest of San Francisco 49ers linebacker Ahmad Brooks on charges he assaulted a teammate has been put on hold amid a debate in the Santa Clara County District Attorney's Office over whether Brooks should be charged with a felony or a misdemeanor -- or not at all.

The controversy stems from a June 8 incident in which Brooks allegedly struck 49ers nose tackle Lamar Divens three times in the head with a beer bottle and then punched him in the face during an argument over car keys outside Brooks' house in San Jose. The alleged attack left Divens bloodied and requiring three stitches, according to court documents.

At the time, Divens said he wanted to press charges, but he has since changed his mind, according to the warrant application. The alleged attack was also witnessed by two other unidentified team members, one of whom gave a recorded statement to police.

Sounds like Divens talked to somebody and now he remembers he just fell down some stairs.
