Kentucky won 45-44! 1 point safety

[johnnybgood]

During the 3rd overtime, Kentucky had the ball first, scored a touchdown and had to go for 2. Tennessee player intercepted on his 5, had possession, and fumbled backward into his own end zone. Loose ball was batted and hit the pylon clearly (obvious on multiple angle replay), which is a safety! Score 1 point for Kentucky! The lead 45-38. Tennessee scores a touchdown and has to go for 2. Conversion fails. 45-44, game over.

So either 1-point safeties are not allowed during the 3rd overtime in NCAA, or the refs blew this game, changing the fortunes of several teams. The 1-point safety is definitely allowed in the 2nd overtime, so what gives?
