Kansas City and Seattle have swapped linebackers, with D.J. Alexander joining the Seahawks and Kevin Pierre-Louis being sent to the Chiefs.
The clubs made the trade Friday on the cusp of training camp for both teams.
Alexander issued the following statement on Instagram following news of the deal:
Pierre-Louis never matched his potential with the Seahawks. An exceptional athlete, Pierre-Louis struggled with injuries and with inconsistent performance when he got on the field. Pierre-Louis appeared in 34 regular-season games with one start. He had 43 total tackles playing outside linebacker for the Seahawks.
