FAYETTEVILLE, Ark. - The Arkansas football team went through its first two-a-day practices on Saturday with a one-hour morning practice that focused on the kicking game and an hour and a half scrimmage in the afternoon inside Donald W. Reynolds Razorback Stadium. The 65-play scrimmage was slowed and eventually cut short after injuries hampered the Hogs progress. Right tackle Zac Tubbs went down with a high-right ankle sprained early in the scrimmage for the first team. Cornerback Michael Grant then left a short time later with what appeared to a dislocated finger. Sophomore quarterback Robert Johnson had a good scrimmage under center for the Razorbacks and may be creating a little separation in the quarterback battle. "I thought Robert Johnson had a very good day of executing," Nutt said. "He was throwing it well and doing a very good job of getting us out of the wrong play and into the right one. He managed the 25-second clock and did all of those small things that you take for granted when you had a quarterback that was here for four years like Matt (Jones)." Johnson and his offensive teammates took advantage of a defensive squad that did not have one of their better days. "Defensively, we didnt play as well today," Nutt said. "We didnt tackle as well, and we werent ready to play. They (the defense) had been real good the past two days and when you put it (the ball) down live, sometimes it wakes you up a little. I have no doubt that the defense will wake up and get better tomorrow." The Razorbacks will return to the practice field again tomorrow in shells to correct todays mistakes before starting a full week of two-a-day practices.
