LANDOVER, Md. -- Washington Redskins running back Adrian Peterson, inactive a week ago, moved up to fifth place on the all-time rushing touchdown list after his 1-yard score in the second quarter of Sunday's loss to the Dallas Cowboys, snapping a tie with Jim Brown.

Peterson, running out of I-formation, was stuffed for no gain on first down but muscled through for the score on second down for the 107th TD of his career.

"Man, it's a blessing," Peterson said after Washington fell to Dallas 31-21. "It just continues to show me how blessed I am to continue to play this game in year 13, to have the opportunity and ability to pass the greats who paved the way. He was the first one that paved the way for us.

"This one means a lot more than the other ones will when I pass them because Jim Brown is a guy I looked up to. I had the opportunity to talk to him on several occasions and just the look in his eyes when I'm talking to him it's just like... it's motivating to me. It feels good to have passed him today but it's bittersweet because we didn't get this divisional win."

With running back Derrius Guice on injured reserve, Peterson got the start, a week after he was a healthy inactive in the season opener at Philadelphia. Guice tore his right meniscus, and there's a good chance he'll return in Week 11 once he's eligible to come back.

Last season, Peterson rushed for 1,042 yards and seven touchdowns while playing in all 16 games. He entered this season eighth on the all-time list with 13,318 yards.

Peterson ran for a team-high 25 yards on 10 carries Sunday.
