Rookie cornerback Nnamdi Asomugha took one more step toward working his way back into the mix Sunday.
Asomugha injured his shoulder on the second day of training with his MRI examination resulting negative. Asomugha, whom the Raiders drafted in the first round from California, has been limited to mostly individual work the past two weeks but participated in teamwork Sunday.
"It felt good to be doing some competitive work," Asomugha said. "There was a little soreness afterwards. Just getting reps and seeing plays again was the main thing."
Asomugha suited up for warm-ups before the Raiders 7-6 exhibition win over St. Louis but did not play. Asomugha will participate in the team's padded practice Monday as Oakland prepares for Thursday's exhibition game at San Francisco.
"He looked like a normal guy that hasn't been in much contact," Oakland head coach Bill Callahan said. "His footwork and change of direction, his ability to cut, plant and break to the ball was pretty good. Tomorrow will be a big day."
Asomugha also knows that the more he was limited, the further he would fall behind. Asomugha had been projected to compete for playing time in the Raiders nickel defense.
"It was killing me to watch because I wanted to be out there," Asomugha said. "We're going to be smart this week and make sure I'm ready to go."
Asomugha added that he tried to stay up to speed by watching film.
"It hasn't been that difficult," Asomugha said. "I'm a film guy anyway. I've had to double it up mentally."
