The No. 4 overall pick in the 2015 NFL Draft had 48 grabs for 680 yards and seven scores in 14 games during his 2017 campaign. He is in the NFL’s concussion protocol after suffering the head injury in the Raiders’ Week 6 loss to the Seattle Seahawks.
The Raiders now have three first-round picks in the 2019 NFL Draft.
Cooper — a two-time Pro Bowl selection — has two games with at least eight catches and 100 receiving yards this season. Cole Beasley is the only Cowboys receiver to have at least 100 receiving yards in a game this season, doing so in Week 6 against the Jacksonville Jaguars.
The 2018 NFL trade deadline is on Oct. 30.
