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.

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

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?

As the Colts prepare to take on the Seahawks, Indianapolis still hasn't decided if Riley Leonard or Philip Rivers will start.

Leonard directed eight offensive possessions that produced one touchdown and two field goals. But he also got tackled in the end zone for a safety and was intercepted at the Jacksonville 45-yard line. Running back Jonathan Taylor ended Leonard’s first full possession by losing a fumble at the Colts 28-yard line.

Colt's rookie QB is listed in full practice after knee injury. He may play in Sunday's game against the Seattle Seahawks

An already chaotic Colts quarterback situation has become worse with the revelation from Colts head coach Shane Steichen on Monday afternoon that rookie third-string turned backup turned starting QB Riley Leonard suffered an injury to his right knee during Sunday’s road loss to the Jacksonville Jaguars.

The Colts listed rookie quarterback Riley Leonard as a full participant in Wednesday’s practice. Leonard is dealing with a knee sprain suffered during Indianapolis’ loss to Jacksonville on Sunday. But he was at least healthy enough to take his usual reps to start the practice week.
