The offensive line was hit on Tuesday when starting offensive tackle DeMarcus Love suffered a left knee injury in the morning practice and starting offensive guard Grant Cook hurt his left knee in the afternoon practice.
"I saw (Love) after practice and he was upbeat," Arkansas offensive line coach Mike Summers said. "So we're encouraged."
Love missed the afternoon practice, and the extent of his injury is unknown. Summers didn't provide any details about the junior, though he said Cook's injury doesn't appear to be serious.
"I think Cook is all right," Summers said. "They told me he could come back at the end of practice."
Arkansas coach Bobby Petrino was unavailable for comment, and school officials didn't provide details on any of the day's injuries.
Wide receiver Greg Childs (toe injury) and tight end Ben Cleveland (left shoulder) were also injured in the morning practice and sat out the afternoon session.
• Along with the injured players, several other Razorbacks were noticeably absent from Tuesday's afternoon practice, including tight end D.J. Williams, wide receiver Lucas Miller, safety Anthony Leon and running back Adrian Moore. Moore has been dealing with an academic issue, Miller is coming back from a torn anterior cruciate ligament and Williams appeared to get injured in the morning practice.
• Sophomore Jerry Franklin returned to the first-team defense, though he was working at middle linebacker instead of his usual outside linebacker spot. Linebacker Bret Harris also worked with the first defense, while senior captain Wendel Davis continued to serve his demotion to the second team.
• Arkansas defensive tackle Malcolm Sheppard was named Tuesday to the Outland Trophy watch list. The award is given annually to the nation's top interior lineman.
"It would be an honor to hopefully one day win something like that," Sheppard said. "But right now it's a team thing."
Running back Dennis Johnson made an immediate impact as freshman last season when he served as Arkansas' primary kickoff returner. But he has been slowed over the past few days by injuries, opening the door for freshman tailback Ronnie Wingo Jr. to get more work returning kicks.
And so far, Arkansas special teams coordinator John L. Smith has been impressed with what he's seen from the speedy freshman.
"He could be a kickoff return guy. I mean, there's nothing etched in stone with any of the guys back there," Smith said of Wingo. "But I tell you what, we really like his toughness. We like him on the special teams that he's been on ... and you take a look at a guy like that as a kickoff return guy.
"He's a big body that can really run, so you want to take a look at him (and) give him every opportunity to be a guy back there."
Johnson set an Arkansas single-season record with 905 kickoff returns yards last season, and he returned a kickoff 96 yards for the go-ahead touchdown in a 30-23 win over Tulsa. But he hasn't been guaranteed the kickoff return duties.
