INGLEWOOD, Calif -- Los Angeles Chargers wide receiver Quentin Johnston exited the opening series of Saturday night's 23-22 preseason loss to the Los Angeles Rams on a medical cart after a hit that left him motionless on the field for several minutes.
Head coach Jim Harbaugh said that Johnston suffered a concussion and was taken to a local hospital for X-rays and further evaluation.
"That's never a good thing, but the way it looked there at the time looked like it could have been a lot worse," Harbaugh said.
Harbaugh added: "He was talking, he remembered the play, he was moving good.
