Dunn, a Bethesda native who walked on to the Terps roster as a true freshman in 2012, started 48 games over his career in College Park, primarily at left tackle. He was named an All-Big Ten honorable mention in 2015 and 2016 and last season helped Maryland rush for over 2,500 words for the first time since 2003.
"Knowing my projection as a Day 3 guy or undrafted free-agent guy, I know I'll be somewhere come August," Dunn told Glenn Clark Radio in March. “I've already been in a place where I've had zero expectation for me and I've proved everybody wrong. I'm confident enough in my abilities that I can do the same thing all over again."
Former Terps cornerbacks Alvin Hill (Cleveland Browns) and Will Likely III (New England Patriots) and wide receiver Levern Jacobs (Washington Redskins) also have signed with NFL teams after going undrafted.
