Chidera Uzo-Diribe played defensive end at Colorado for four years. Over the past three months, he has been learning to play linebacker with hopes of being drafted by an NFL team this spring.

At 6-foot-3 and 252 pounds, Uzo-Diribe is undersized for defensive end in 4-3 schemes at the pro level. He's perfectly suited to play the outside linebacker spot in a 3-4 defense because he would often be asked to rush the quarterback with some coverage responsibilities.

Uzo-Diribe said several teams that employ 3-4 defenses showed interest in him in January when he participated in the East-West Shrine game. He believes he helped himself with his performance Wednesday at Colorado's pro timing day.

"I felt like I had a good day other today and showed the athleticism and the speed," he said.

Uzo-Diribe led the nation for much of the season last fall in forced fumbles. He also is among Colorado's career leaders in sacks.

"This is a passing league," he said. "So if I can show that I can pass rush at the next level, every team has a place for pass rushers. If I can stand out from the others and show that I can pass rush and drop out in coverage, that will just help my case."

Nine former Buffs worked out for 26 scouts from 24 NFL teams Wednesday afternoon in the Dal Ward Center weight room and the practice bubble.

Wide receiver Paul Richardson is considered the most likely draft pick in the group. He left school early to enter this year's draft after a record-setting junior season. Richardson participated in only a few drills and ran routes with CU offensive graduate assistant T.C. McCartney throwing him passes. McCartney played quarterback at Fairview High School and was a walk-on quarterback at LSU.

In addition to Uzo-Diribe and Richardson, longsnapper Ryan Iverson, offensive lineman Gus Handler, defensive back Parker Orms, linebacker Derrick Webb and defensive lineman Nate Bonsu worked out. They were joined by former teammates Travis Sandersfeld and Doug Rippy who were in the 2012 and 2013 draft classes, respectively.
