Arkansas suffered its first major injury of preseason camp on Wednesday morning when tight end Chris Gragg had to be carted off with a severe ankle injury.

  Arkansas coach Bobby Petrino said he believes Gragg dislocated his left ankle and will likely need season-ending surgery. The sophomore’s injury leaves the Razorbacks thin at tight end while starter D.J. Williams continues to miss practice with a minor ankle injury.

  ”I feel bad for him. He’s worked extremely hard,” Petrino said of Gragg. “I’m sure it’ll be a situation where he’ll have to have surgery and be out the year.”

  Arkansas athletic trainers rushed to Gragg after he suffered the injury midway through Wednesday’s practice. As he was being carted off the field, the tight end gave a thumbs up to the small crowd inside Reynolds Razorback Stadium that cheered for him.

  Williams has missed the past two practices after injuring his ankle Tuesday morning. Petrino said he didn’t known when Williams will be healthy enough to return to practice, adding that “hopefully” it will be soon.”

  With Williams and Gragg out, former Springdale High star Ben Cleveland got more reps at tight end. But Cleveland isn’t fully healthy, either. He said he was bothered Tuesday by a neck stinger, and he has battled a toe injury and nerve damage in his neck during his time with the Razorbacks.

  Arkansas began two-a-day practices today, so I thought I’d drop a few tidbits from the morning practice on the blog before I eat lunch and then head back for the afternoon practice at 4 p.m.

  Tight end Ben Cleveland missed much of the morning practice after suffering an apparent left arm injury. It looked like he hurt his shoulder and was forced to sit out the team portion of practice.

  Linebacker Bret Harris continued to work with the first-team defense. Meanwhile, fellow sophomore Jerry Franklin is back with the first-team defense, but he has moved over to the middle linebacker spot. Senior Wendel Davis, who coaches have criticized over the first week of practice, is still working with the second-team defense.

  Offensive tackle DeMarcus Love had a scary moment when he went down with an apparent left knee injury. It didn’t look good, but after a few minutes down, he was able to get up and walk around on his own power. Redshirt freshman Matt Hall filled in for Love on the offensive line.

  There was some running back news as well.

  Adrian Moore continued to miss practice because of an academic issue. Meanwhile, Dennis Johnson and Broderick Green have been slowed by injuries over the past two days. 

  And finally, quarterback Tyler Wilson continued to have problem taking the snap. He fumbled two snaps, both of which were recovered by defensive end Jake Bequette.
