CINCINNATI — No points in the second half.

More penalties than first downs.

The Bengals’ playoff chances were extinguished with a fitting meltdown.

A 24-20 loss to the Pittsburgh Steelers on Sunday took care of the defending division champions. Cincinnati (5-8-1) had its club-record streak of five playoff seasons snapped.

They lost in the first round each season, and still haven’t won a playoff game since the 1990 season.

How they faded hurt the most.

The Bengals matched the club record with 12 wins last season, only to lose at home to Pittsburgh in the opening round of the playoffs.

Jeremy Hill’s fumble and penalties on Vontaze Burfict and Adam “Pacman” Jones moved the Steelers in range for the winning field goal in the final seconds, one of the biggest meltdowns in playoff history.

They melted down again in the second half on Sunday.

After scoring on their first four possessions for a 20-9 halftime lead, they managed only 38 yards in the second half. They had more penalties (seven) than first downs (four).

Burfict and Jones got flagged again Sunday — the linebacker for tackling Roethlisberger after he got rid of the ball, and the cornerback for taunting. The Bengals were left fuming.

“They let Pittsburgh do whatever they wanted to,” cornerback Dre Kirkpatrick said. “They should’ve been calling stuff on them, too.”

The Bengals had one take-that moment while building the lead. Hill scored on a 4-yard touchdown run, saw a Terrible Towel that a fan had thrown onto the field, picked it up and tried to tear it. Unable to do that, he threw it to the ground again.

“It was just lying there,” Hill said. “Spur of the moment.”
