"My experiences at UCLA have provided me with great confidence and I can't wait to represent my Bruins in the NFL," Benenoch tweeted Thursday.
Benenoch's departure further weakens an offensive line already lacking in depth. Before the Foster Farms Bowl, junior guard Alex Redmond left early for the NFL draft, and freshman Fred Ulu-Perry, who had been expected to compete for the starting center job, transferred to Hawaii. The Bruins had just six healthy, active linemen for the game.
Next season, the only returning starters will be guard Kenny Lacy and left tackle Conor McDermott, if both choose to stay with the Bruins.
Benenoch started all three seasons at UCLA, mostly at right tackle. This season, he shuttled between tackle and guard.
He is the fifth UCLA underclassman to declare for the NFL draft.
UCLA Coach Jim Mora could not be immediately reached for comment.
