One more down. Two left to go.

The Vikings this morning announced that they had signed sixth-round pick Antone Exum. Exum was a standout safety and cornerback at Virginia Tech, starting 35 of his 44 games there, but he was limited by injury to just three games in 2013. He will play safety for the Vikings.

The team also announced that first-round pick Anthony Barr, who agreed to terms yesterday, had officially signed his rookie contract, too.

The Vikings have now signed eight of their 10 draft picks. The two who have not yet signed are defensive end Scott Crichton and running back Jerick McKinnon. Both were third-rounders.
