WATCH: Desmond King lights up Steelers on 73-yard punt return TD

Jake Roth-USA TODAY Sports

The Pittsburgh Steelers had everything going for them Sunday night against the Los Angeles Chargers.

Then, Ben Roethlisberger threw a bad interception to Derwin James, Philip Rivers and Co. benefited from a pinball touchdown following a vicious collision by two Steelers defenders, and then the Chargers got a defensive stop.

On the impending punt, with roughly 13 minutes left in the game, Desmond King changed the complexion of the contest with an incredible 73-yard punt return touchdown.

Rivers converted the two-point conversion, and suddenly the game was all knotted up at 23-23.

Just a stunning turn of events at Heinz Field for “Sunday Night Football.”
