OWINGS MILLS, Md. -- His voice cracking with emotion, Baltimore Ravens running back Ray Rice acknowledged Friday that he "failed miserably" and apologized for the actions that led to his arrest on assault charges.

Rice was arrested after a Feb. 15 altercation in Atlantic City, New Jersey, in which he allegedly struck fiancee Janay Palmer. The couple married in late February, and both went to the stage at the team training complex for their first public comments since the arrest.

"I failed miserably, but I wouldn't call myself a failure because I'm working my way back up," he said.

Wearing a light gray suit and striped tie, Rice spoke for just over six minutes and didn't take questions. His speech was not prepared, but he often referred to notes on his cellphone.

"I know many of my supporters, sponsors, don't want to be in partnership with me. That's my fault," Rice said. "I take full responsibility for that. One thing I do know is that I'm working every day to be a better father, a better husband and just a better role model."

Rice was accepted Tuesday into a diversion program, which upon completion could lead to the charges being expunged.

"I want you to know I'm still the Ray Rice that you know, or used to know, or grown to love," Rice said. "I'm still the same guy. As me and Janay wish we could take back 30 seconds of our life, we definitely sit here and tell you that we are better parents, we are better lovers and also better friends."

Among those in attendance were Rice's mother, Janet, and his father-in-law, Joe Palmer. Rice was only 5 when his father was shot and killed, and he referred to Joe Palmer as the "father I never had."

"Thank you for teaching me how to be a man," he told Palmer. "I know it wasn't easy when you saw everything that happened, but I just remember your words: 'You'll get through it.' Those words will always stick with me, because one thing you gave me is trust."

Ravens general manager and executive vice president Ozzie Newsome and coach John Harbaugh did not attend the news conference due to previously scheduled out-of-town commitments, the team said.
