A year after letting top wide receiver DeSean Jackson go , Chip Kelly has again put his stamp on the Philadelphia Eagles with a jaw-dropping piece of business . Two-time All-Pro running back LeSean McCoy will be traded to the Buffalo Bills in exchange for third-year linebacker Kiko Alonso . The stunning trade will reunite Eagles head coach Kelly with former Oregon star Alonso , who is coming off ACL surgery after a dominant rookie year in 2013 . LeSean McCoy will move to Buffalo to work under new head coach Rex Ryan . Kiko Alonso will be reunited with Chip Kelly as he looks to recover from ACL surgery . McCoy was regularly sidelined in favour of Chris Polk during the Eagles ' disastrous stretch , which saw the Dallas Cowboys claim the NFC East title . The move should end CJ Spiller 's time in Buffalo and further confirms the devaluation of the running back position . Freeing up $ 11.95million in cap space , the move adds fuel to the fire that the Eagles will move up for former Ducks quarterback - and Kelly protege - Marcus Mariota in April 's draft . ESPN 's Adam Schefter first reported the trade , with NFL.com 's Michael Silver confirming the move .
LeSean McCoy , 23 , heads to Buffalo after one year in college . He rushed for 1,319 yards and 11 touchdowns last season for the Eagles . Kiko Alonso , 24 , missed all of the 2014 - 15 season with a torn ACL . In his rookie season , he completed every defensive snap and ranked third in the NFL with 159 tackles .
