If you want a seat for the March Madness games at Ball Arena, there’s still time on the clock. But the pep band has already started counting down the final seconds.

“They’re pretty much sold out,” Mountain West Conference senior associate commissioner Javan Hedlund told The Post late last week.

The Mountain West is the hosting body for the NCAA men’s tournament first- and second-round games downtown, a four-day window that starts with practices open to the public on Wednesday, with tilts to follow on Thursday and Saturday.

Hedlund said fewer than 30 tickets remained for each of the two first-round sessions on Thursday and for the single session in the second round on Saturday.

Each session features two games.

Tickets are available via secondary market sites. StubHub.com as of Friday evening offered “get-in” prices as low as $102 including fees for Session 1, with a “get-in” low of $99 including fees for Session 2.

All-session tickets on the site had a low “get-in” price of $400 including fees as of Friday.

The lowest “get-in” price for Saturday’s second-round session was $197 with fees.
