Denver’s stunning 29-23 AFC Wild Card victory over Pittsburgh Sunday scored huge numbers for CBS.

The game, highlighted by Tim Tebow’s 80-yard touchdown pass on the first play of overtime, averaged a 25.9 overnight rating — the biggest overnight Wild Card numbers in 24 years (since Seattle-Houston snared a 26.7 in January 1988 on NBC).

Sunday’s game peaked with a 31.6 from 8 to 8:15 p.m., according to Nielsen.

Denver, which was the underdog going into Sunday’s matchup against the Steelers, blew a two-touchdown, fourth-quarter lead — at home — before Tebow connected on his 80-yard pass to Demaryius Thomas.

Over on Fox, meanwhile, the Giants’ dominating 24-2 Wild Card victory over Atlanta averaged 28 million viewers and was up 1 percent over last year’s NFC Wild Card Game on CBS.

The game peaked with 31.1 million viewers at 3 p.m.

The Tebow-led Broncos will play New England next weekend.

The Giants head to Green Bay to play the Packers at Lambeau Field.
