Saquon Barkley accomplished many firsts at Penn State, and now he can add one to his professional football list.

The former Nittany Lions tailback and 2017 unanimous All-American selection made plenty of big plays in the program's famous black NIKE cleats, and he must have liked the feel of them, as he'll wear them in the NFL, too, now that he has signed an endorsement contract with the company.

ESPN's Darren Rovell reports that the Coplay, Pa., native is the first draft-eligible prospect to announce an endorsement deal ahead of the 2018 NFL Draft in Dallas, Tex.

Back in January, Barkley picked an agent, as he signed with Roc Nation Sports, and he continues to train for the NFL Combine, which will be held in Indianapolis, Ind., at the end of the month.

He also turned 21 on Friday.
