In the very first game of the '09 season he came racing down the field on a kick coverage and stopped a BYU return man dead in his tracks.
Hurst may have developed a knack for making huge special team's hits, but last Saturday he got a chance to play in the Red River Rivalry game when senior corner Brian Jackson left the field because of a tender ankle.
Obviously Texas wanted to put pressure on the true freshman corner, but the Longhorn's plan did not work.
He defended one pass and then on the next play he blitzed and made one of the game's biggest plays when he sacked Colt McCoy for a 15-yard loss.
The play helped preserve a 6-0 OU lead. The Sooners would end up losing the game to the Longhorns 16-13. But Hurst made his mark in his time on the field in a game filled with importance.
"Demontre – a true freshman – came in when Brian Jackson was a little dinged up and made a huge sack," OU head coach said when asked of Hurst's play.
"He did a nice job in his fundamental coverage too. He played with good technique and he competed well. He did an excellent job and we didn't miss a beat at that point."
Jackson hated to miss any of the snaps in the game, but he was happy to see Hurst play so well, especially since he is a guy that the senior has taken under his wing.
"I tried to take him under my wing and show him the ropes a little bit from two-a-days," Jackson informed. "He came right in and surprised a lot of us. He is really athletic and being a track guy. When I saw him come off that corner on that blitz and get that sack – I was over there getting taped and I was still excited for him."
"He is a great competitor. He is a wonderful kid and he is going to really great things around here."
So far as a true freshman Hurst has racked up seven tackles, a sack, and has broken up a pass attempt.
