Pyne, listed as a 6-0, 205-pound linebacker, graduated from Brown University this month with a degree in History and will join the Buffs on January 13 for the start of the spring semester.
"He's a highly productive defensive player," CU coach
Mel Tucker said. "He plays multiple positions; he could play inside linebacker or at our star position. I've known about him all the way back to his days at IMG, where he was a team captain. He'll come in and compete for playing time. We're very excited about him."
Pyne played for Brown from 2016-19 and has one season of eligibility remaining. He started the last three seasons and was the team's leading tackler as a senior. In his last three seasons at Brown, he accumulated 178 tackles (103 solo) with 14.5 for a loss and a sack. He added six pass breakups, three quarterback hurries and two forced fumbles.
