4Q update: Ohio State 30, Illinois 13

Posted by ESPN.com's Adam Rittenberg

CHAMPAIGN, Ill. -- Ohio State appears to have this one in hand, thanks to opportunistic play and the dominant rushing attack of Terrelle Pryor and Chris Wells.

Pryor set up a touchdown run with a graceful 26-yard scamper, and Dan Herron punched it in from 12 yards out. The Buckeyes will move to 9-2 and keep their Big Ten title hopes alive, while the Illini need to win next week to get bowl eligible.

It's been a rough day for Illinois junior safety Donsay Hardeman. First, Wells hurdled him on a 25-yard run that will be replayed countless times on SportsCenter. Then, he got flagged for a debatable unsportsmanlike conduct penalty after Illinois appeared to stop Ohio State on third-and-4.

Terrelle Pryor's pass had hit Dan Herron and was going to fall incomplete when Hardeman leveled wide receiver Dane Sanzenbacher. Officials said the penalty occurred after the play, which is impossible since the ball was still in the air, though the viciousness of the hit caused the flag.

I'm heading down to the field for interviews, but check back later for more updates.
