Petrino not sure which brother will start at QB

Posted by ESPN.com's Chris Low

Arkansas coach Bobby Petrino isn't ready to make a call on who will be his starting quarterback this Saturday against Mississippi State.

Senior Casey Dick has been the Hogs' starter all season, but he was knocked out of the game with a concussion two weeks ago in the 34-21 loss to South Carolina.

Petrino is thinking seriously about going with Dick's younger brother, redshirt freshman Nathan Dick, against the Bulldogs.

"We're going to have to wait and see how (Casey) reacts to everything and see how the week of practice goes," Petrino said. "Whether he'll be the starter or Nathan will be the starter, we certainly feel confident with either one of them starting."

Dick is second in the SEC with 2,389 passing yards, but he's thrown 14 interceptions, including three against the Gamecocks.

"It wasn't Casey's best game of the year against South Carolina," Petrino said. "He made some mistakes prior to getting hit in the head. Also, you want to make sure Mississippi State has to prepare for both of them."

Petrino said tailback Michael Smith should be ready after injuring his shoulder in the South Carolina game. Smith didn't practice during the bye week, but returned to the practice field Monday night and looked good, according to Petrino.

"I think his legs are back and feeling good," Petrino said.

Smith has rushed for 1,012 yards and caught 30 passes this season. No running back in SEC history has ever rushed for 1,200 yards and caught 40 or more passes in the same season. Smith would be in select company if he rushes for 1,100 yards and catches 35 passes, as only a handful of SEC players have done that.
