If the Collins injury is serious, the Colts may consider signing another quarterback and that quarterback could be familiar to the Chiefs, according to the Indy Star.
Croyle, who wasn't re-signed by the Chiefs, spent about a week with the Arizona Cardinals in the preseason.
QB Curtis Painter came in for Collins last week so a lot of things would have to go wrong in Indy for the Chiefs to see Croyle in Week 5.
