Raiders wide receiver Darrius Heyward-Bey was informed at a prehearing conference Thursday that he’s due back in court July 23 for his next go-round as a result of his being charged with driving under the influence.

Heyward-Bey, 25, went before Superior Court Judge Donna Little in San Francisco. He was arrested and charged in the early morning hours of April 7.

The Raiders begin training camp in Napa on July 29. Coach Dennis Allen last month said he and the Raiders are keeping tabs of Heyward-Bey’s legal issue.

“It’s a situation we’re aware of and we’re monitoring,” Allen said.

Heyward-Bey could not be reached for comment.
