College basketball's regular season is coming to a close and by the end of Sunday, we'll know which teams are going to be competing in both the men's and women's NCAA Division I tournaments. Final selections for the men's tournament will happen at 6 p.m. ET with the women's selections following at 8 p.m. Each tournament will feature 68 teams.

March Madness then officially begins on Tuesday with the First Four round in the men's tournament. The play-in round will determine the four lowest-seeded teams in the tournament.

The pandemic is ongoing, but the tournaments are back to a more normal schedule with different rounds taking place in cities across the country instead of the entire tournament in one place.

The NCAA released COVID-19 guidelines this month outlining testing and vaccination policies.

If you're looking to get in on the fun this month, here's a schedule of the tournaments, a look at building your own brackets and more as the road to the Final Four begins.
