Young is a defensive end from Iowa Western Community College and is originally from Des Moines, Iowa. He spent this season at Iowa Western and committed to Louisville on Monday after a visit last weekend.
The 6-foot-4, 225-pound Young had 45 tackles in his one season at Iowa Western, including 13.5 sacks and 20 tackles for a loss.
Young picked U of L over Mississippi, Iowa and Iowa State. He had been committed to Western Michigan until recently when his phone started blowing up with major college offers.
"Trevon Young is a very athletic defensive end who matches our pressure style of defense," U of L recruiting coordinator Brian Jean-Mary said. "He can play in space as a stand up outside linebacker and rush the passer as a down lineman. We are excited to have him in our program as we believe he will be a great addition to our already talented defensive line."
Young was recently named a National Junior College Coaches Association second-team All-American. Iowa Western, ranked No. 3 in the national junior college rankings, finished the season at 11-1 with a 6-0 win over Butler in the Graphic Edge Bowl.
He's the only JUCO signee for the Cardinals this season. He will begin classes at U of L on Jan. 6 and will be able to participate in spring practice.
