Life is moving in fast-forward for rookie quarterback Riley Leonard since he grabbed his helmet and ran onto the field to replace injured Indianapolis Colts starter Daniel Jones in Jacksonville last Sunday.

After Daniel Jones' injury, the course of the Colts' season might now be determined by a sixth-round rookie QB. But who is Riley Leonard?

And you thought it couldn't get worse, Colts fans. Quarterback Riley Leonard has a knee injury, status for Sunday is unknown

The Indianapolis Colts had been in a strong position to make the playoffs all season, but recent circumstances have changed that outlook. Starter Daniel Jones tore his Achilles last week, while sixth-round rookie Riley Leonard has yet to make a start.

The most likely out of these three is that the Colts trust Jones' rehab enough to retain him on a short-term deal. Initially, it was believed the Colts were preparing to give Jones a long-term deal, given how well he was playing and fitting with Shane Steichen's offense. Obviously, that is now a murky subject.
