Prosch, a key player in Auburn leading the nation in rushing last season, was selected by Houston Texans with the 35th pick of the sixth round, which is the 211th overall pick in the draft.
The winner of the Football Writers Association of America's Courage Award said that he is eager to prove he belongs in the NFL. "I feel like there are a lot of ways I can help the team," he said.
"Playing fullback, obviously I am a physical blocker, but I can do more than that," he added. "I can run, I can catch and move around. I am also available to play special teams so I can do more than just line up and block."
Prosch played two seasons for the Tigers after transferring from the University of Illinois, where he was a standout performer. He made the move to be closer to his mother in the Mobile area, who was suffering from cancer and passed away just before the start of the 2013 football season.

Scott Fountain, Prosch's position coach in his role as an H-back with the Tigers, has a high opinion of the Texans' draft pick. "I feel like Jay is Auburn," Fountain said. "When you look for an Auburn football player, Jay is the type of guy you look for because he is tough, gritty and will do whatever it takes to help the team.
"I think that things worked out very well for Jay at Auburn and I will be surprised if he doesn't play for the next 10 years in the NFL," Fountain added. "I think he is going to be a great team guy at the next level."
Prosch did not have any carries as a senior. He caught five passes for 95 yards with one touchdown. As a junior he had 12 carries for 38 yards and two scores while catching five passes for 19 yards
Auburn's four players drafted are the most since the 2011 draft when four Tigers were selected. Last year defensive end Corey Lemonier was the only AU player drafted going to San Francisco in the third round.
