Running back Tyler Gaffney hasn’t finished classes at Stanford, but he’s already signed his first professional contract.

The Panthers announced that Gaffney agreed to a four-year deal with the team during this weekend’s rookie minicamp. He will have to return to Stanford until school’s out, forcing him to miss offseason time with the team.

“Stanford is on the quarter system, so it will be like June 9 before we see him again,” General Manager Dave Gettleman said, via the team’s website. “That hurts. That makes it difficult to work.”
