Richardson (knee) isn't listed on Wednesday's injury report.
In the Colts' 31-21 loss to Jacksonville in Week 1, Richardson came out of the game for the final three offensive plays due to a bruised left knee, but both the quarterback and head coach Shane Steichen downplayed the injury after the game. The rookie's omission from the Week 2 injury report confirms that Richardson is healthy heading into Sunday's game in Houston, where the rookie signal-caller will look to pick up the first win of his NFL career after throwing one touchdown and rushing for another in his debut.
