Rice hurt his knee during the fourth quarter of last Sunday's 24-17 victory over the Cleveland Browns. An MRI on Monday revealed no ligament or cartilage damage.
"Once you hear the good news of nothing being torn and it's just a bruise, I felt great," Rice said Thursday. "It's just getting better each day. I'm just going out there working because I know it's just a bruise. I got a second opinion, got everything I needed to do. Once you find out it's just a bruise, you've got new life again."
Willis McGahee and Le'Ron McClain will take the brunt of the carries if Rice can't play. However, Rice doesn't intend to sit out the Ravens' showdown against the unbeaten Steelers, who lead the AFC North.
"We have a great corps of backs, but I'm sure I'll be ready to play," Rice said.
"He'll see how I look in practice," Rice said. "Right now, I feel great."
Although he didn't practice Wednesday, Rice said he was able to run and cut a little bit on his own.
"If I'm able to do the things I can do and be the Ray Rice I can be, there's no question on whether I'll play or not," Rice said. "At the end of the day, Sunday's the ultimate test."
Rice is certain the Steelers won't target his knee Sunday.
"I don't think they're dirty," Rice said. "I don't think anybody has the intent to go out there and hurt anybody. I have respect for them, they have respect for us. I don't think it's going to be one of those situations where they're going to take a blatant shot at the knee."
