Uko posted his decision on his private Twitter account, and the USC official Twitter account revealed the news:
— #25 USC Trojans (@USCTrojansFO) December 31, 2013
Uko had 36 tackles, seven tackles for losses and five sacks in 2013 and was named All Pac-12 honorable mention for the second year in a row. He finishes with 85 tackles, 17.5 tackles for losses and 11.5 sacks.
The loss of Uko is a blow to a USC interior defensive line that is expected to be a strength of the team in 2014, with ESPN All-American Leonard Williams, Antwaun Woods, Kenny Bigelow, Texas Tech transfer Delvon Simmons and incoming junior college signee Claudeson Pelon.
