Colts' Anthony Richardson suffers injury on running play

Richardson went to the sideline for two plays and then returned. On his first play back in the huddle, the Colts called a designed run for the quarterback. Richardson appeared to have trouble moving and voluntarily dropped to the turf after gaining a few yards.

Joe Flacco replaced Richardson after that play. Richardson was taken to the locker room and ruled out for the remainder of the game a short while later.

Richardson had his rookie season cut short last year due to a shoulder injury. That injury occurred on a running play as well, which you can see here.

One of the reasons Richardson has found success early in his career is that he is a legitimate dual-threat QB. That has also left him susceptible to injuries, which has become a problem for the former Florida star.
