San Francisco 49ers coach Jim Harbaugh said Tuesday that the team has a zero tolerance policy on domestic abuse.

"I'll be very clear," Harbaugh said, two days after 49ers defensive end Ray McDonald was arrested on felony domestic violence charges. "You ask me how I feel about domestic violence. I can be very clear about that. If someone physically abuses a woman and/or physically or mentally abuses or hurts a child, then there's no understanding, there's no tolerance for that."

A player found guilty of domestic violence would be removed from ther roster, Harbaugh said.

"We can be very clear" about that, he emphasized.

"There are going to be two principles at play here. And one is, I'll speak for myself, I'll speak for the 49ers: We'll not tolerate domestic violence. The second principle, we're firm believers in due process. And I ask for your understanding on those two principles."

According to a Sacramento Bee report, McDonald was arrested early Sunday during a party in honor of his birthday after his fiancee showed bruises on her body to police that allegedly came from an altercation with McDonald. Nine other 49ers players were attending the party, the Bee reported.

McDonald said after posting $25,000 bond on Sunday that the "truth would come out" about the "crazy situation." The 49ers continue to investigate the matter.
