Tray Matthews and Kamryn Pettway will begin their NFL careers as undrafted free agents.

The former Auburn safety and running back each said they signed with the Minnesota Vikings as UDFAs following the NFL Draft on Saturday. They'll join former Auburn kicker Daniel Carlson, who the Vikings drafted in the fifth round earlier Saturday.

Matthews had 59 tackles with one sack, an interception, two pass breakups and a fumble recovery in 13 games last season. He participated at the Senior Bowl, but did not play in the game and did not get invited to the Combine, though he performed well at Auburn's pro day.

His 22 bench press reps would've been third among 21 safeties at the Combine. Matthews also had a 35.5-inch vertical jump, 10-foot-1-inch broad jump and ran the 40-yard dash in 4.54 seconds, which would've placed 10th, 11th and 12th, respectively, among safeties at the Combine.

In 2016, Matthews led Auburn with 76 tackles and had an interception and three pass breakups.

He had surgery on both of his shoulders following the 2015 season and dealt with minor hamstring injuries at various points in his college career, which began at Georgia in 2013.

Pettway dealt with heel, ankle and shoulder blade injuries while rushing for 305 yards and six touchdowns in five games last season after leading the SEC in rushing yards per game in 2016.

He ran for 1,224 yards and seven touchdowns and led the SEC with 122.4 yards per game in 2016 and was aiming to break Auburn's single-season rushing record last season, but began the year with a one-game suspension due to a failed drug test for marijuana, played through plantar fasciitis, hurt his ankle and later fractured his shoulder blade.

Pettway left Auburn with one year of eligibility remaining and faced questions about his character during the pre-draft process.

He ran the 40-yard dash in 4.74 seconds, 26th among 28 running backs to run at the NFL Combine. His 33.5-inch vertical jump was 14th among 28 backs and his 9-foot-8-inch broad jump was 17th out of 22 backs, though his 22 bench press reps tied for fifth among the 29 backs to lift.
