Sources told ESPN's Chris Mortensen that Carson Wentz, the Indianapolis Colts quarterback, will be starting Sunday against Tennessee Titans. Wentz was injured in Week 2 and had to withdraw both of his ankles.

Wentz was able to practice on Friday and will be relied on Sunday when the Colts attempt to win their first ever championship. Although heavily taped, Wentz was able to move around quite well during the practice that was open to the media.

He is now 45-of-69 with 498 yards, three touchdowns and an interception in his first season at Indianapolis. He has been sacked six more times than usual and was also hit 21 times during those two losses.

It is not known what the backup plan will be for Sunday, whether it's Jacob Eason or Brett Hundley.

Since entering the NFL in 2016, Wentz has only played one full season since he was drafted No. 2nd overall draft pick in 2016.
