Jalen Sami, a defensive tackle from Vista Ridge High School in Colorado Springs, announced on Twitter that he would play football for the Buffaloes and sign his letter of intent on Wednesday.
"I'm glad to announce that I will be continuing my education & football career at CU Boulder!" Sami tweeted.
The 6-foot-5, 325-pounder is a late bloomer. As of Saturday, his only scholarship offers were from Northern Colorado and CSU-Pueblo.
Sami visited the Buffs last weekend and received an offer on Sunday. He also received a late offer from Ole Miss on Monday.
Sami fills a need for the Buffs, who were hoping to sign a prep prospect to play nose tackle in their 3-4 defense.
In December, the Buffs signed JUCO transfer Javier Edwards to play nose tackle, hoping he can fill a hole immediately. Now, they will also get a chance to develop Sami.
