Indianapolis Colts quarterback Daniel Jones sustained a torn Achilles in the Colts' Week 14 loss to the Jacksonville Jaguars on Sunday according to head coach Shane Steichen. That injury turns the 49ers' Week 16 showdown with the Colts on its head and turned the Monday night contest into a more winnable game for San Francisco.

Leonard in his first NFL season is completing 58.1 percent of his throws with 145 yards and one interception in two games. Indianapolis was scuffling down the stretch, but they were still formidable with Jones under center and running back Jonathan Taylor in the backfield. The 49ers host the Tennessee Titans on Sunday with a chance to move to 10-4, which they're favored heavily to do.
