The 29-year-old, who was the number one pick at the 2012 draft, has seen his career dogged by injuries. He missed the entirety of the 2017 campaign after having shoulder surgery, but was the NFL’s Comeback Player of the Year last season as he returned to lead the Colts to the playoffs for the first time in four years.
