"We're going to take a look at some young guys and see what they can do and go from there," linebackers coach John Jancek said.
With Verdun Wheeler starting in the middle last week in place of an injured Jackson, Ole Miss' BenJarvus Green-Ellis rushed for 135 yards, his highest total of the season, and Richt wasn't shy about placing the blame on Verdun Wheeler.
"I think it had a pretty strong contributing factor there," Richt said. "I think Danny Verdun understands what to do and was in the right spot, but when it came to the moment of truth, that human equation, linebacker versus running back, we didn't knock (Green-Ellis) back, he knocked us back."
Jackson is the Bulldogs' lightest linebacker but also their most physical.
"Jarvis has been the guy that can really run through ball carriers," Richt said. "He tends to be the big hit guy for us."
Jackson, who has battled a painful foot injury all season, played against Ole Miss but had only three tackles. His foot feels much better this week, he said Tuesday.
