What happened: Ian Rapoport and Mike Garafolo reported the move Sunday. Houston originally selected Clowney first overall in 2014.
Why it matters: Houston adds veteran edge depth with time to establish his role before Week 1. Dallas must replace the 8.5 sacks he produced last season.
By the numbers: Clowney spent five seasons with Houston and totaled 29 sacks during that run.
What to watch: Clowney's first preseason practices will begin to define his place in Houston's edge rotation.
