The Vikings and third-round pick Josh Robinson have agreed to a contract, leaving first-round selection Matt Kalil the team's only unsigned draft choice on the eve of training camp.
The Vikings announced the agreement, first reported by Pro Football Talk.
Robinson, a cornerback, was the 66th overall pick.
Kalil, the fourth overall selection, is one of five first-round picks who has yet to agree to terms.
The others are receiver Justin Blackmon (fifth overall by Jacksonville), quarterback Ryan Tannehill (eighth overall by Miami), defensive tackle Dontari Poe (11th overall by Kansas City) and receiver Kendall Wright (20th overall by Tennessee).
Vikings players will report to Mankato tomorrow.
