Sam Pittman and Arkansas football put forth a tremendous comeback effort to earn the upset win against Tennessee in Week 6.

Arkansas football coach Sam Pittman entered the season on the hottest seat in the country. That seat is only getting cooler after an upset win over Tennessee.

The Razorbacks upset No. 4 Tennessee (4-1, 1-1 SEC) 19-14 on Saturday night after backup quarterback Malachi Singleton scrambled for a game-winning 11-yard touchdown with 1:17 remaining in the fourth quarter. Tennessee had a late hoorah, headlined by a 42-yard catch, but it wasn't enough.
