Mingo, a pass rusher out of LSU, was the No. 6 overall pick in the 2013 NFL Draft.
The Plain Dealer reported, via a league source, that Mingo's contract is worth more than $16 million and contains offset language. The Browns and Mingo's camp previously had been haggling over the presence of offset language in the deal.
A dynamic athlete, Mingo will be expected to contribute right out of the gate to the aggressive defense run by coordinator Ray Horton. Mingo, who this offseason received a heaping of praise from former SEC offensive linemen, said last month he believes the Browns' defense can be the best in the NFL.
