The Philadelphia Eagles have a trade in place to send running back LeSean McCoy to the Buffalo Bills, a source told ESPN NFL Insider Adam Schefter.
In return, the Bills will send linebacker Kiko Alonso to the Eagles, the source said.
Drafted in the second round of the 2009 draft out of Pittsburgh, McCoy has spent his entire six-season career in Philadelphia.
He rushed for 1,319 yards and tallied five touchdowns last season for the Eagles.
The trade can not be made official until the new league year begins next Monday.
