-- SAN FRANCISCO -- A Santa Clara County grand jury has indicted former San Francisco 49ers defensive lineman Ray McDonald on one count of rape of an intoxicated person.
The announcement came Wednesday, with the indictment stemming from an incident Dec. 15 at McDonald's home.
Current 49ers linebacker Ahmad Brooks also has been charged by the Santa Clara County District Attorney's Office with misdemeanor sexual battery for an alleged assault the same day involving the same victim. The case against Brooks was announced Wednesday.
Messages left for McDonald's attorney and Brooks' agent weren't immediately returned.
"The organization is aware that a misdemeanor charge has been filed against Ahmad Brooks stemming from a December 2014 matter. We take any charge against a member of this organization seriously and are in communication with the NFL. Ahmad is returning home to California and will not participate in Saturday's game," 49ers general manager Trent Baalke said in a statement released by the team.
In a civil lawsuit filed in May against both men, a woman accused Brooks of groping her while she was unconscious at McDonald's home.
The woman said she slipped and fell on a pool deck at McDonald's house in December 2014 and continued to fall after that due to her initial head injury and alcohol consumption. McDonald initially thought she was dead but did not call 911, telling others he didn't want a dead female found on his property, according to the suit.
At some point, Brooks groped her before McDonald carried her upstairs to his bedroom and sexually assaulted her, the lawsuit claimed.
McDonald, an eight-year NFL veteran who turns 31 on Sept. 2, was indicted nearly a year after another incident while celebrating his 30th birthday.
In that incident, he and his pregnant fiancee got into a fight after a woman attending the party told her some women were getting too friendly with McDonald. McDonald's fiancee, who was sleeping upstairs, came down and confronted him, according to a prosecutors office memo.
Following McDonald's arrest in that case, 49ers CEO Jed York, Baalke and then-coach Jim Harbaugh repeatedly said they had zero tolerance for domestic violence, but rather than bench McDonald, they agreed to let "due process'' play out before making a decision about his future with the team.
However, in December, the Niners parted ways with McDonald, citing a "pattern of poor decision-making." He had been a key member of one of the NFL's fiercest front-seven units.
McDonald signed a one-year contract with the Chicago Bears in late March, but the team released him two months later after he was arrested on suspicion of domestic violence and child endangerment.
Brooks, 31, had his own problems last year and his status was uncertain going into the offseason, but he had begun training camp with a new outlook and was back in shape thanks to a rigorous offseason routine.
He had started 60 straight games under fourth-year coach Harbaugh before being benched for a 24-13 loss at Oakland because he missed a team meeting. Brooks said after the game that he inadvertently missed a morning defensive meeting Dec. 2 but showed up an hour later for a second meeting focused on domestic violence. Then-defensive coordinator Vic Fangio said Brooks also arrived 20 minutes late to a Dec. 3 meeting, and the coach didn't know why.
Brooks later apologized.
He also was benched Nov. 16 for the second half of a 16-10 road win against the Giants for heated words he directed at defensive line coach Jim Tomsula -- now the Niners' head coach -- in the second quarter.
