ATHENS — Linebacker Brandon Miller is definitely out for Georgia’s game at Vanderbilt on Saturday, but receiver Mikey Henderson will make the trip.

Henderson is hobbled by a hamstring injury.

"He has got a medical clearance to play," coach Mark Richt said after Thursday’s practice. "But he doesn’t feel 100 percent, and he feels like if we do too much it could cause a problem."

Henderson ranks second on the team with 14 receptions for 136 yards, with one touchdown. He has started three out of six games for No. 24 Georgia (4-2, 2-2 Southeastern Conference).

"Initially, we were like, ‘Let’s not do anything,’ but the more we think about it and the more he feels a little bit better as the week goes along, you feel like let’s get him in position to help," Richt said.

Miller, who has started four games, injured his calf during agility drills this week and won’t be able to play. The Bulldogs also will be without running back Thomas Brown, who broke his collarbone in last week’s 35-14 loss at Tennessee.

The Bulldogs will likely start redshirt freshman Akeem Dent at strongside linebacker, with Dannell Ellerbe in the middle and either Darius Dewberry or freshman Rennie Curran at the weakside spot.

Dent has made one start, in a win over Western Carolina when he tied for the team lead with six tackles. Curran earned a shot at more playing time by making seven tackles in a loss to Tennessee last weekend.

CONFIDENCE PROBLEM

The Bulldogs seem to do just fine when things are going their way from the opening kickoff.

It’s a lot different when they get off to a sluggish start.

Last week, Georgia had no answer as Tennessee raced out to a 28-0 lead. Richt blames his team’s youthfulness for its tendency to feed off the momentum, whether it’s good or bad.

"It’s immaturity," the coach said. "I just don’t think we’re a real mature team. We’ve been up and down. We’ve not had a consistent effort throughout the season.

"Maybe it’s a confidence issue," he added. "But I just think we’re young, more than anything. We’ve not gotten to the point where we can overcome things like fatigue and the momentum going against you. We’ve got to do better at that. We’re going to harp on that this week. We’ve got to start creating our own momentum."

NO CHANGES AT PLAYCALLER

Even though Georgia has struggled a bit offensively under new coordinator Mike Bobo, Richt hasn’t felt the urge to start calling plays again.

The head coach turned over those duties to Bobo late last season and has no intention of changing the arrangement.

"I give some input throughout the week," Richt said. "On game day, if I see something glaring that I think needs to be said, I’ll say it. But a lot of times, other people have a thought process that is just as good as mine, or a guess process that is just as good as mine."

Bobo is operating at a bit of a disadvantage with a young offensive line — three freshmen are set to start against Vandy — and a banged-up running game.

"If I see something that I think might be helpful, I’ll say it during the game," Richt said. "Otherwise, I’m staying out of it pretty good."
