Yahoo SportsLittle-known Chiefs rookie makes the biggest play in a huge win over Chargers

Everyone found Amazon Prime Video's stream on Thursday night to watch Justin Herbert vs. Patrick Mahomes. Instead, Jaylen Watson ended up being the star of the show.

Jaylen who? Watson was a seventh-round pick of the Kansas City Chiefs in this year's draft.

He stepped into a big role for Thursday night's game because first-round pick Trent McDuffie was out due to an injury.

In a game full of big-name players, Watson made the play that decided it.

In the fourth quarter of a tie game, Watson picked off a Justin Herbert pass near the goal line and returned it 99 yards for a touchdown

That changed the entire game, as the Chiefs went on to a 27-24 win in a game that will loom large all season in the AFC West race.
