OAKLAND -- Raiders running back Darren McFadden was back Thursday night, but maybe not for long.
After missing four weeks with a high right ankle sprain, McFadden rushed for 52 yards on 11 carries and caught a 6-yard touchdown pass in the second quarter of a 26-13 loss to the Denver Broncos at O.co Coliseum.
By the end of the game, McFadden was back on the sideline, and in the postgame locker room, he was getting treatment on the same right ankle that cost him a month of the season.
"We just got off the field, so I don't really know exactly where it is, I just know he wasn't able to finish the game," coach Dennis Allen said.
McFadden got off a 36-yard run on the first play of the second half against a Denver defense that hadn't given up a run longer than 24 yards all season. He also dropped the first pass thrown to him, a ball in the flat, and had just 9 net yards on his last five carries.
The return of McFadden led to Marcel Reece getting just four carries for 10 yards and Jeremy Stewart being inactive.
"We wanted to give him an opportunity to get the ball, and we did that," Allen said. "We only had 47 plays, so it's really hard to get a lot of people a lot of work."
Cornerback Michael Huff didn't finish the game because of a wrist injury.
Allen said Adams can expect increased playing time based on the last two games.
"I was just doing what I was told. It wasn't nothing too crazy," Adams said. "If it wasn't for my other teammates, I wouldn't have made the play."
"We had a plan to give Khalif some chip help. I thought we did a nice job of it in the first half," Allen said. "We weren't able to protect as well against him in the second half."
The first came by Lamarr Houston late in the first quarter, coming up the middle on third-and-8 from the 14.
Denver made it as far as the 10 on its next possession until Desmond Bryant sacked Manning for a 6-yard loss on second-and-9, with Manning throwing incomplete on third-and-15.
On Denver's last possession of the first half, a safety blitz from Mike Mitchell with Denver at the Oakland 49 helped defuse Manning's effort to tack on a score after the Raiders had scored their lone touchdown.
Before the game, Goodell participated in a panel discussion promoting the 50th year of the Hall of Fame along with John Madden, John Elway, Ronnie Lott and Howie Long for 150 Raiders season-ticket holders. Then the commissioner spent about six minutes fielding questions from the media.
Goodell said the ratification of a collective bargaining agreement has created a stability that should make for a more favorable environment with regard to getting a stadium built.
"It does a great job of making sure the economics are balanced among all 32 teams and of course the players," Goodell said. "We have also got a new stadium funding mechanism in there that the league can provide up to $200 million of financing to a new stadium project.
"I think those are very significant changes."
Goodell said any idea of sharing the 49ers stadium would have to come from the two teams. It's an option both teams have said publicly is not off the table, but neither organization has made any move in that direction.
"The priority is what the community and the team work out," Goodell said. "I think it's a great benefit that there's a stadium across the bay that's going to be a state of the art facility. That's terrific. So that's an option if those communities and the Raiders choose that. But that's a decision they have to make."
Goodell deflected a question about the glacial movement toward a stadium between the Raiders, the city of Oakland and Alameda County.
"You all are closer to it than I am," Goodell said. "I think people want to make sure the Raiders are here and want to make sure they do the right things; there are a lot of priorities in communities these days, and those have to be balanced by the leadership both in the public sector and the private sector.
"These are complicated issues, and they have to be done intelligently so that they address community needs but they also work with the team long term."
Rookie Rod Streater caught four passes for 100 yards, including a 58-yard strike from Palmer on the play immediately preceding an interception by Champ Bailey in the first quarter.
Seymour has missed the last five games with a hamstring strain.
