Los Angeles Chargers wide receiver Quentin Johnston was carted off the field following a big hit on the opening series of the team's preseason game against the Los Angeles Rams on Saturday evening. The injury occurred when Johnston tried to haul in a pass from Chargers quarterback Justin Herbert , only to take a hit from Rams safety Tanner Ingle .
Chargers coach Jim Harbaugh said after the game that Johnston was diagnosed with a concussion and taken to the hospital as a precaution.
The injury initially appeared to be quite serious, as Johnston remained down on the field for several minutes as trainers attended to him and began preparing a stretcher for him. Johnston was eventually able to sit up, but was visibly frustrated as he was carted off the field.
