Oakland Raiders defensive end Mario Edwards Jr. was carted to the locker room with an apparent leg injury during Friday's preseason game against the Arizona Cardinals.
Edwards suffered the injury when a teammate fell on his leg as he brought down Cardinals running back Chris Johnson.
The 22-year-old started 10 games for the Raiders last season after being selected in the second round of the 2015 draft out of Florida State.
Below is a video of how Edwards suffered the injury:
