When Seattle Seahawks receiver Ricardo Lockette fell to the turf in Dallas and didn't move last season, and when he stayed down for a long time after, you knew he had just suffered a very serious injury.
As it turns out, the hit ended Lockette's career.
Lockette will announce his retirement on Wednesday, NFL Network's Ian Rapoport said. It's a tough blow for Lockette, who worked himself onto the Seahawks roster as an undrafted free agent, only to have his career end on one of the most devastating hits in recent NFL history.
