PITTSFORD, NY — The Buffalo Bills completed a pair of blockbuster trades on Friday, in deals that will send wide receiver Sammy Watkins and cornerback Ronald Darby out of Buffalo, the team announced.

The Bills acquired CB E.J. Gaines and a 2018 second-round pick from the Rams in exchange for wide receiver Sammy Watkins and a 2018 sixth-round pick.

Just a minute later, the team announced a trade that will send Darby to the Philadelphia Eagles in exchange for wide receiver Jordan Matthews and a 2018 third-round pick.

The Bills basically filled the voids left by Watkins and Darby with Matthews and Gaines, and loaded up on more draft picks in the process. The Bills now have two 2018 first-rounders, two 2018 second-rounders and two 2018 third-rounders in next year's NFL Draft.

Matthews is a former second-round pick (42nd overall) who has missed just two games over his three-year career. He has 225 catches for 2,673 yards and 19 touchdowns in his career. His best season came in 2015 when he had 85 catches for 997 yards and eight scores.

Gaines is a little unknown.

He was drafted in the sixth-round (188th overall) in 2014. He missed the entire 2015 season after he had surgery to repair a lisfranc injury in his foot. He has two interceptions in 26 games.

Gaines figures to be the Buffalo's No. 2 cornerback opposite rookie Tre'Davious White.

This is a developing story and will be updated soon.
