The Giants selected him third overall in the third round, one spot ahead of where the Browns likely would've selected him.
It's not yet known what round the Browns bid, but it was probably the third.
The Browns had the fourth pick in each round of the draft behind the Raiders, Jets, and Giants. The Broncos rounded out the top five.
Selection order was determined by a lottery among three groups of teams (six or few wins, more than six wins but no playoffs and playoff teams).
The Browns learned of their draft order shortly before the draft started at 1 p.m.
In the sixth round, the Redskins selected Virginia Tech defensive back Adonis Alexander, meaning the Browns did not bid on him in that round, even though they expressed some interest.
It marked the first time two players were selected in the supplemental draft since 2010. They were also the only two players selected out of the five in the draft. The other one who had a chance to be drafted was Mississippi State defensive back Brandon Bryant.
Beal (6-foot-1, 196) was ruled academically ineligible for 2018, but Western Michigan coaches and school officials loved him, sources told cleveland.com.
The Browns were expected to bid on him and possibly groom him to start somewhere down the road opposite Denzel Ward, the No. 4 overall pick this year.
"With Sam Beal, you're intrigued by the athleticism and the size combination,'' NFLdraftscout.com draft analyst Rang said. "There's just not many corners that are a legitimate six-foot that can just change directions and accelerate as fluidly as he does. He's a terrific athlete. At the same time, he's still a little bit raw as a football player. He's not a great run-enforcer and he doesn't have the interceptions and things of that nature that you'd love to have at that level of competition.''
In the absence of Beal, the Browns have several candidates for the No. 2 cornerback job, including T.J. Carrie, E.J. Gaines, Terrance Mitchell and Briean Boddy-Calhoun. In OTAS and minicamp, Carrie got the most reps with the first-team defense.
