Colbert resigns; NFL comeback

USC's Keary Colbert has decided to resign from his position as tight ends graduate assistant to make a comeback attempt at the NFL, the school announced Monday.

Colbert, 28, was a four-year receiver for the Trojans from 2000-2004 and once held the school's all-time receptions record. He was a second-round pick of the Carolina Panthers in 2004 and set a number of franchise rookie records.

He then spent the next several years with the Panthers, Denver Broncos, Seattle Seahawks and Detroit Lions.

"After spending a year working with the tight ends at USC as a graduate assistant, it ignited my passion and fire to compete at the highest level," Colbert said in a statement. "I've been training and getting myself physically prepared to make a comeback in the NFL. I plan to be a great veteran addition to any team's wide receiver corps."

Colbert was being considered for the vacant receivers coach job by Lane Kiffin. USC now has at least two vacancies on the coaching staff.
