Defensive end Jeremy Lomax is suffering from a turf toe injury, Richt said, and did not scrimmage with the defense Monday. Running back Knowshon Moreno, who has been battling a sore shoulder, also missed Monday's action.
With safety Quintin Banks out with an MCL tear, his potential replacements showed signs of progress, Richt said. Redshirt freshman John Knox tallied four tackles and freshman Bacarri Rambo racked up six stops and a pass break-up during Monday's scrimmage.
Walsh hit all three of his kicks in Monday's scrimmage, including field goals from 36, 37 and 38 yards.
"One of the field goals Walsh made was in the one-minute drill," Richt said. "We needed a field goal to win that drill, and we were in range, and he made it."
Sophomore Andrew Jensen, Walsh's primary competition for the starting job, also converted on his lone attempt, a 36-yarder.
