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.

Expect 4-13 and 5-12 matchups at Ball Arena

The NCAA selection committee “protects” better seeds — that is, to say, its 1, 2 and 3 seeds — with first- and second-round sites that are the closest to their respective campuses.

CBS Sports bracketologist Jerry Palm as of Friday evening projected Auburn, his top seed in the South, to land in Lexington, Ky., while assigning projected 1 seeds Florida (West) and Duke (East) to start their journeys in Raleigh, N.C.

However, teams from the “4” line on down tend to land more random assignments after the top seeds are accounted for. Which is where Denver comes in, as the Front Range is not considered geographically advantageous to any of the top dozen or so teams in the field.

Palm’s projected bracket as of early Friday night had Ball Arena hosting third-seeded Texas A&M against No. 14 Utah Valley and No. 6 Memphis vs. No. 11 West Virginia in one pod. The other pod would see No. 4 Purdue take on No. 13 High Point and No. 5 Ole Miss face No. 12 Drake.

ESPN’s Joe Lunardi as of early Friday evening had No. 3 Kentucky vs. No. 14 Utah Valley and No. 6 Illinois vs. No. 11 VCU in one pod, with No. 4 Texas A&M vs. No. 13 Yale and No. 5 Clemson vs. 12th-seeded McNeese in the other.
