FAYETTEVILLE -- Arkansas running back Darren McFadden said Monday that he's feeling "pretty good" two days after being bothered by bruised ribs.

As a precaution, the Heisman Trophy candidate underwent a routine scan Monday. The scan showed that McFadden doesn't have any cracked or fractured ribs.

"I think he's feeling much better. He had a scan today on the rib cage, and I think he's doing good," Arkansas coach Houston Nutt said Monday afternoon. "I talked to the doctors. (They said) that he's going to be fine."

McFadden is expected to practice this afternoon and play Saturday night when Arkansas hosts No. 22 Auburn in Reynolds Razorback Stadium.

"I anticipate he'll be fine," Arkansas athletic trainer Dean Weber said. "I anticipate he'll probably practice (Tuesday)."

The bruised ribs appeared to bother McFadden in last Saturday's 34-15 win over Tennessee-Chattanooga in War Memorial Stadium in Little Rock.

The junior rushed for a season-low 122 yards and one touchdown on 25 carries, and he also fumbled the football twice in the first half.

McFadden said his fumbles were less about his sore ribs and more about him not securing the football properly. But he admitted that the injury had been bothering him in the days leading up to the game.

"It was a little sore all week. It's been sore and just probably a lot of the pounding I took (Saturday) just added to it," said McFadden, who stands 32 yards shy of becoming Arkansas' all-time leading rusher.

Despite the injury, McFadden said he's not about to change his running style to protect his ribs. He's a physical runner, period.

"That's my running style and I don't feel like that's something I can just change in the middle of my career," McFadden said. "It's something I've been doing for the past 10, 11, 12 years, so it's something that I'm probably going to stick with."

Injury Update

Arkansas wide receiver Robert Johnson, who missed Saturday's win because of a foot injury, is expected to practice today.

Meanwhile, Nutt said he doesn't expect wide receiver Marcus Monk to make his long-awaited return Saturday night.

"Boy, I'd love to say yes," Nutt said when asked Monday if Monk had a chance to play against Auburn. "I just don't think he's going to be ready."

Monk, who was Arkansas' leading receiver last season, has missed the first five games of the season while rehabbing from a second arthroscopic surgery on his right knee.

Harrison Pleads Not Guilty

Arkansas defensive tackle Marcus Harrison pleaded not guilty Monday to four misdemeanor charges stemming from his Aug. 24 arrest for speeding and possession of Ecstasy and marijuana.

Harrison pleaded not guilty to the charges of possession of a controlled substance, not wearing a seat belt, driving on a suspended license and failure to appear. The failure to appear charge involved another incident.

Harrison's plea was phoned into Fayetteville District Court on Monday morning. His trial is set for Dec. 12.

The senior also has a trial set for Nov. 20 in Washington County Circuit Court relating to his felony charge of possession of an Ecstasy pill.

Harrison was suspended for the Sept. 1 season opener against Troy University, but he rejoined the team the following week.

The Little Rock native has started two games this season, and he has six tackles in four games.
