Nebraska is going to have to monster holes to fill in the middle of its defensive line.

Two weeks after Maliek Collins announced his intentions to forgo his final year of eligibility and declare for the NFL draft, his running mate followed suit.

Husker defensive tackle Vincent Valentine announced via Twitter on Monday that he’ll also be turning pro.

Valentine was one of Nebraska’s key run-stoppers as a three-year starter.

He helped lead a unit that finished ninth in the country against the run at 109.8 yards per contest. The 6-3, 320-pound junior struggled with injuries during the 2015 season, but he still managed four tackles for loss and three sacks.

He doesn’t project to be a potential first-round pick like Collins, but Valentine certainly has the size to make him an NFL defensive tackle. His draft stock could depend largely on his pro day.

Without Collins and Valentine, the Huskers will turn to Kevin Maurice to step into a major role in 2016.
