head coach Tom Cable punched one of his assistants on Aug. 5 at the team's training camp headquarters in Napa, Calif., several media outlets reported on Monday.
The Web site National Football Post first reported that defensive assistant Randy Hanson was punched in the jaw by another member of the Raiders staff. Unidentified sources later told Fanhouse.com that Cable hit the third-year assistant.
Hanson reportedly did not want to pursue the matter, but staff at Queen of the Valley Hospital alerted authorities, according to Fanhouse.com.
"The victim didn't even want any police action taken," Napa Police Lt. Brian McGovern told the Web site, "but we were following hospital policy that authorities be contacted in cases where there may have been an assault."
