Well, now we know what made the Chiefs take an offseason flier on Terrelle Pryor.

The team announced via its official website that quarterback Tyler Bray suffered a torn ACL, which sparked the Pryor move. Bray will have surgery soon to repair the damage, which should keep him from being ready for the start of the regular season.

Pryor signed with the Chiefs earlier this month, so they’ll have him around this offseason to take snaps behind Alex Smith and Chase Daniel.

Bray spent the year on injured reserve after suffering knee and ankle injuries in the preseason finale. The Chiefs also have fifth-round pick Aaron Murray, who didn’t play a game last year after suffering a torn ACL near the end of his college career at Georgia.
