That second half saw Arkansas run wild in the third quarter and put up 17 points in the second half after being shut out in the first half.

Courtney played so well against the Commodores that he was named the SEC Offensive Lineman of the Week.

When the depth chart for Saturday's game against No. 23 Missouri was released on Monday, Kitler was listed above Courtney, and there was no "or" designation listed as there has been for many players this year.
