COLUMBIA -- Garrett Chisolm is big, even if he isn't big on attention.

The 6-6, 290-pound South Carolina walk-on lineman has worked his way into the Gamecocks' starting lineup.

Chisolm has twice shied away from interview requests, making him the team's mystery man.

The West Ashley product will start at left guard Saturday at Arkansas. He played right guard for an extended period this past week at Tennessee.

Coach Steve Spurrier is certainly high on Chisolm.

After spending time at a small college in Kentucky and a community college in Charleston, Chisolm wound up on USC's campus.

He came out for the team this summer, and walk-on coordinator Jamie Speronis gave him a spot on the scout team.

Chisolm didn't even start practicing with the team until the middle of August.

He quickly made a name for himself.

"I remember one day coach Lorenzo Ward said, 'That new kid over there has knocked our guys on their butts,' " Spurrier recalled. "I said, 'What? Yeah, that new guy. What's his name?' "

Someone told him.

"'(Fifth-year senior tackle Nate) Pepper and them guys, they don't like going against him all that much,'" Ward told Spurrier.

After a few weeks, Chisolm started working with the scholarship players.

Now he's expected to get his first start.

Spurrier said he appreciates Chisolm's attitude. He said he almost always shows up early to meals and meetings.

"He's got a wonderful attitude that hopefully will rub off on all these other players," Spurrier said. "As a coach, you love those kind of guys. You love those guys that really act like this is important to them."

King out

In addition to the attrition the defense is experiencing, the offense will be without big left tackle Jarriel King this week.

King suffered a mild concussion during the Tennessee game.

Sophomore Kyle Nunn is expected to start at left tackle against Arkansas.

"They think he got bonked in the head somehow," Spurrier said of King, a North Charleston native.

Spurrier added that King actually went to the hospital Saturday night, but he checked out OK. He sat out practice Monday. He was expected to return to practice Tuesday, but only in non-contact drills.

Lessons learned

Akeem Auguste said Tuesday that a little catnap cost him his start Saturday at Tennessee.

Ward said Monday that Auguste overslept the defense's 3 p.m. meeting before the game in Knoxville. That's why C.C. Whitlock started over him.

"It was one of those quick naps, and I overslept," Auguste said. "It won't happen again. Coach has no favoritism, so I didn't start."

Auguste was suspended for the South Carolina State, Kentucky and Alabama games. Tennessee was his second game back.

"I let my teammates down emotionally," he said. "I had a talk with my teammates, a heart to heart, really. I let them know I wasn't going to let them down again and I learned my lesson."

Auguste is expected to start Saturday at free safety for Chris Culliver, who is both injured and suspended.
