ATHENS — Saturday was a day of ingress and egress for the Georgia Bulldogs. Some were coming back in while others were going out.

The Bulldogs are down at least two players as head coach Kirby Smart revealed that offensive lineman Mirko Jurkovic had to undergo surgery for a dislocated kneecap and defensive lineman Joseph Ledbetter is “not with the team right now.”

Jurkovic is a redshirt freshman tackle out of South Bend, Ind., who Smart indicated did not appear to be contending for a starting position. Smart declined to expound on Ledbetter’s departure. The 6-foot-4, 240-pound junior is the older brother of sophomore defensive end Jonathan Ledbetter.

The Bulldogs did get back linebacker Tim Kimbrough. The senior missed practice this past Thursday for what at the time were unknown reasons.

Smart shed some light on that.

“He’s got some academic issues he needed to focus on,” Smart said following the Bulldogs’ scrimmage Saturday. “So we allowed him to miss practice to focus on the academic situation he’s in. He’s centered on that work. Of course we had him back out there today, but he was focused on his academics there for a 48-hour window.”

Tailback Brendan Douglas was back in a black non-contact jersey and held out of the scrimmage on Saturday. He was held out for precautionary reasons after returning to full-go status this past Thursday from off-season wrist surgery.

Fullback/tailback Nick Moore also was out due to what Smart said was an MCL knee injury. That left the Bulldogs shorthanded again in the backfield. As a temporary fix, they moved receiver Shaquery Wilson to running back

“He got to play a little bit in special situations,” Smart said. “I’m glad we did because we would have run out of backs today. He got to play a little bit back there.”
