If the Raiders actually are trying to trade wide receiver Amari Cooper, they're swinging for the fences on the return.

One day after Fox Sports reported the Raiders are shopping Cooper and safety Karl Joseph, NFL Network's Ian Rapoport said the team wants a first-round draft pick in return for the wide receiver.

As Rapoport explained Monday, asking for a first-round pick might make a deal hard to complete.

"My understanding is [the Raiders] have asked for a first-round pick for Amari Cooper, which seems incredibly significant and might make it difficult, if not impossible to trade him," Rapoport said.

Cooper, 24, was a first-round pick himself, taken by the Raiders No. 4 overall in the 2015 NFL Draft.

Cooper is in the midst of an inconsistent 2018 season, catching 22 passes for 280 yards and one touchdown. On Sunday, his day was cut short when he took a vicious helmet-to-helmet hit in the first quarter and later was ruled out with a concussion.
