Update on Justin Herbert's injury: Despite a rib injury, Chargers coach Brandon Staley claims the quarterback is "OK."

After the Los Angeles Chargers game on Thursday night, nobody is disputing Justin Herbert's tenacity, but there might be some uncertainty regarding his availability in the near future.

On a hit from defensive end Mike Danna in the fourth quarter against the Kansas City Chiefs, the Pro Bowl quarterback went down hard and appeared to be in discomfort for a few minutes.

He was seen clutching his left side as the game entered the commercial break.

Herbert only missed one play, despite how rough he appeared to be before the break.

Before Herbert returned to the game, dependable backup quarterback Chase Daniel substituted Herbert for one play, a pass to running back Sony Michel.

But it didn't take long for Herbert to begin to exhibit signs of ongoing discomfort.

The 24-year-old raised concerns at one point when he tossed the ball away rather than running for a simple first down because he appeared to be moving cautiously before and after plays.

On the very next play, Herbert was able to hit wide receiver DeAndre Carter with a 35-yard dart, though.

facilitating a touchdown that extends the game. Some athletes are simply built differently.
