Warrum has been ISU's leading receiver the past two seasons with a combined 118 receptions and 26 touchdown catches.

"I just wanted to get a foot in the door and show them what I can do," Warrum said. "I'm going to mini camp. We're still working out the details. I could still sign (as a free agent) with them."

Bello spent his final season as a Redbird after transferring from Illinois.

"The beginning of the seventh round they were calling me saying they were trying to draft me. I guess it didn't work out," Bello said of the Browns. "Right after the draft my phone started going crazy. I felt like they had the best interest for me, and I could really fit in with what they wanted to do."

O’Shaughnessy headed to Pats: Former ISU tight end James O’Shaughnessy, the last Redbird to be selected in the NFL draft in 2015, was traded during the draft Saturday by Kansas City along with a sixth-round pick (216 overall) to New England in exchange for a fifth-round choice (183 overall).

"I had no clue it was coming. I was casually eating breakfast when I got the call," O'Shaughnessy said. "They said we need you on a flight at 2 and ready to go Monday."
