He was ruled out for the rest of the game and the fear is he tore the ACL in his left knee, according to National Football League medical analyst for SiriusXM and the San Diego Union-Tribune Dr. David J. Chao.
After a 1,400-yard, 14-touchdown season in 2015, Robinson cooled down previous year at Jacksonville quarterback Blake Bortles struggled. Sure his Jaguars blew out the Houston Texans in an impressive manner on Sunday, but Robinson was not a part of it. After hauling in a 17-yard pass on third down from Blake Bortles, he was pushed out of bounds by Kevin Johnson and limped off the field. Even if he only suffered a partial tear of his ACL, he'd likely be out for the rest of the season while preparing to hit free agency in the spring.
Aside from injuries, Bortles' erratic play makes it hard to trust either player as starting options in your lineup. He finished with only 883 yards and six touchdowns.
Given their current standing, Lee should be given first crack as your flex option because he earned favor with the offense in 2016. Robinson was limping badly after the play and struggled to make it to the sideline before collapsing to the ground.
