He was the 168th overall pick of the draft, obtained with the Ravens' compensatory selection.
Wagner was an honorable-mention All-Big Ten Conference selection for the Badgers, missing just one game as a senior due to a right knee injury.
"I waited a little bit longer than I thought I was today, but good things come when they wait and I can't ask for a better organization than the Ravens right now," Wagner said during a conference call. "I'm just thrilled for this opportunity. Just talking and hearing from teams with my agent, I thought I'd go a little bit earlier today, but I'm definitely happy with this. I can't believe I'm a Raven. It's a great organization, I can't wait."
Wagner met with the Ravens at the Senior Bowl and at the NFL scouting combine and talked with run-game coordinator Juan Castillo.
"He's a great guy," Wagner said. "And I can't wait to get going for him."
Wagner is a 6-foot-6, 308-pounder who has run the 40-yard dash in 5.17 seconds, bench pressing 225 pounds 20 times with a 31 1/2 inch vertical leap.
"I'm just a hard worker," Wagner said. "Coming from Wisconsin, we take a lot of pride in our run game and we did a lot of power and a lot of zone. We take a lot of pride in our run game. I think I'm a pretty consistent pass protector as well."
He put on 80 pounds as a freshman after turning down several scholarship offers to lower Division I basketball programs as a high school senior.
"I definitely had a love for basketball early on but as I went through high school, I just thought I had a better future in football and I really fell in love with the game," Wagner said. "Just being offered a walk-on spot at Wisconsin was a perfect opportunity. I always wanted to go there, that was my dream school. I took the opportunity and rode with it and good things came out of it."
Wagner, a native of West Allis, Wis., served an eight-game suspension as a high school senior for violating team rules.
Wagner has experience at both tackle spots, but isn't regarded as an elite athlete. It's likely the Ravens will evaluate him on both sides, but his background in the Big Ten Conference at left tackle should earn him a long look there.
He might be better suited athletically to play right tackle, though.
"No, not right now," Wagner said when asked where he'll line up. "I've played right and left tackle at Wisconsin. Either or, or I'll even move down to guard if that's what they want."
