It was on December 17 when the San Jose Police Department announced they were investigating an alleged incident involving McDonald. An area hospital had notified police the day before that a woman was seeking treatment, and police said the victim said she was possibly sexually assaulted.

Detectives served a search warrant and searched the San Jose home of McDonald.

Rapoport reports that the agent for McDonald, Tom Condon, has sent a letter to all NFL teams, saying McDonald’s counsel was told the news, despite the Santa Clara County District Attorney’s Office not formally announcing its intentions.  McDonald is currently a free agent.

McDonald was released by the 49ers following this latest allegation.  At the time, 49ers general manager Trent Baalke said McDonald had shown “a pattern of poor behavior.”
