Damar Hamlin is just one step away from completing one of the most remarkable comeback stories in the sporting world.

The Buffalo Bills safety reached another milestone in his recovery on Saturday, playing for the first time since suffering cardiac arrest mid-game and needing to be resuscitated on the field on Jan. 2.

Hamlin suited up for the Bills’ preseason opener against the Indianapolis Colts and saw his first live action since his startling and public medical emergency.

After the exhibition kicked off, Hamlin wasted no time getting back to business.

Hamlin made three tackles, including a fourth-and-1 stop of Colts running back Evan Hull for no gain, while playing parts of three defensive series.

Hamlin, 25, received support from players on both sidelines before kickoff, and the Highmark Stadium crowd cheered each time his name was called.

The Bills won the game 23-19, but Hamlin’s successful return overshadowed the outcome.

Assuming Hamlin makes the Bills’ final roster, the last hurdle he faces is playing in his first regular-season game – a milestone that will be undeniably emotional.

After participating in full-contact practices about two weeks ago, Hamlin told reporters about the mental obstacles of returning to NFL football.

“I made the choice to play. But I’m processing a thousand emotions. I’m not afraid to say that it crosses my mind of being a little scared here and there,” Hamlin said at the time. “My faith is stronger than any fear. That’s what I want to preach up here.

“And that’s the message I want to spread on to the world that as long as your faith is stronger than your fear, you can get through anything.”

Hamlin’s long-awaited return to the field was delayed a bit longer as a thunderstorm pushed back the start time of Saturday’s exhibition by a little over an hour.

The Bills open the regular season on the road against the New York Jets on Sept. 11.

Buffalo’s home opener is on Sept. 17 against the Las Vegas Raiders.
