At 6-foot-4, 224 pounds, Kelly is the second big wide receiver slated to meet with team officials.
Indiana wide receiver James Hardy, a 6-6, 220-pound former Hoosiers basketball player, also said the Ravens are one of his official visits.
The Ravens also met with Michigan State wide receiver Devin Thomas at the NFL scouting combine.
Kelly caught 49 passes for 821 yards and nine touchdowns last season, but didn’t work out at the scouting combine due to a strained quadriceps.
As he prepares for the draft, Kelly said he has been privy to some helpful advice from Ravens starting wide receiver and former Sooners star Mark Clayton.
"We talk all the time," Kelly told reporters at the scouting combine. "He just told me it’s going to be a lot more technique. It’s more like a chess game."
For his career, Kelly caught 144 passes for 2,825 yards and 21 touchdowns. Kelly has drawn high marks from scouts for his imposing size, ability to stretch the field and strong blocking skills.
As a sophomore, Kelly caught 62 passes for 993 yards and 10 touchdown catches. However, he incurred some cartilage damage in his knee in the Fiesta Bowl that required surgery.
Durability could be a concern, and it’s probable that the Ravens want to do a thorough medical exam on Kelly.
Plus, Oklahoma tends to be a popular school for director of college scouting Eric DeCosta and defensive coordinator Rex Ryan, a former Sooners assistant coach.
The Ravens, who hold the eighth overall pick, are considered unlikely to use their first-round pick on a wide receiver since they have other pressing needs at quarterback, offensive tackle, cornerback and defensive end.
Although most mock drafts have Kelly going as high as the Buffalo Bills’ pick at No. 11 overall, there are some analysts that have Kelly potentially dropping into the second round due to his injury history.
"My greatest strength is probably just being a deep threat," Kelly said. "That’s the part of the offense I played at Oklahoma, just going down the field and making plays.
"Just good hand-eye coordination no matter where the ball is, being strong and going up and getting the ball out of the air and not waiting for the ball to come down and get you."
