Pitta returned to the field for the first time since dislocating his hip in late July. He remains on the injured reserve designated for return list.
Asked if Pitta could be activated for Sunday's game, coach John Harbaugh said, "There's always a chance. I don't want to say 'no' and then he plays, and I don't want to say 'yes' and he doesn't play. There's always a possibility of (him playing)."
The Ravens would have to activate Pitta by 4 p.m. Saturday and announce a move to make room for him on the 53-man roster.
"We're going to see how I feel (Saturday) and we'll see how it feels (Sunday)," Pitta said, "and we'll go from there."
Pitta was the second-leading receiver on last season's Super Bowl team, catching 61 passes for 669 yards and seven touchdowns. With Pitta out, Dallas Clark and Ed Dickson have combined for 39 catches and three touchdowns in 10 games.
Pitta sounded more optimistic Friday than he did when he spoke to reporters before his first practice Wednesday.
"I feel great. I feel really good," Pitta said. "It's amazing how it can come back. I'm feeling strong and running well. Everything's been positive."
Here is the other injury news:
Defensive tackle Haloti Ngata practiced for the first time in two weeks. He missed last Sunday's game with a knee injury. "We'll just have to see how he comes out of that right now," Harbaugh said. "It'll be interesting to see how he fared and how it feels (Saturday)." Ngata declined comment in the locker room Friday.
Left guard Kelechi Osemele had "successful" back surgery Monday, according to Harbaugh. Osemele is already walking and has visited Ravens headquarters. "He was in a little bit of pain," Harbaugh said. The projected recovery is three to four months.
