Colts' Anthony Richardson: Won't play Monday vs. San Francisco

Head coach Shane Steichen said Saturday that Richardson (orbital) will not be available for Monday's game against the 49ers, Amanda Foster of the Colts' official site reports.

The Colts designated Richardson to return from injured reserve Thursday, but he won't be activated from IR ahead of Monday's game after being a limited practice participant during Week 16 prep. His next opportunity to return is Week 17 against the Jaguars on Sunday, Dec. 28, but even if he does return, he'll likely serve as the Colts' backup quarterback to Philip Rivers.
