March Madness 2023: Selection Sunday, Tournament Schedule, Bracket, How to Watch and More
College basketball’s biggest tournament tips off next week.

The calendar has turned to March, which means madness will soon ensue. The men’s NCAA college basketball tournament — affectionately (and accurately) known as March Madness — gets underway next week. And for the following three weeks, college basketball fans will be treated to small-school Cinderella runs and bracket-busting buzzer beaters.
Here’s everything you need to know to get ready for March Madness, from Selection Sunday to the Final Four and the National Championship game.


The University of Kansas is the defending NCAA men’s basketball champion, and the Jayhawks will enter the 2023 tournament as one of the top seeds.

With 68 teams invited to the big dance, the NCAA holds four play-in games to get the field down to 64, after which point the math works out to have four regional tournaments of 16 teams each. The winners of the four regional tournaments then advance to the Final Four, held this year in Houston.
March Madness begins on Tuesday, March 14, with two play-in games followed by two more play-in games the next night. After these First Four games, the field of 64 is set and the tournament begins in earnest on Thursday, March 16, with a full slate of games that will take place all afternoon and into the night with at least a few moments of madness practically guaranteed.
Which teams are playing in March Madness?
The March Madness bracket and matchups will be revealed this Sunday, March 12. Selection Sunday begins at 6 p.m. ET (3 p.m. PT) on CBS.
What is the March Madness schedule?
Here’s the schedule, round by round:
- First Four: March 14-15
- First round: March 16-17
- Second round: March 18-19
- Sweet 16: March 23-24
- Elite Eight: March 25-26
- Final Four: April 1
- NCAA championship game: April 3
How can I watch March Madness?
As in past years, the tournament will be shown across four channels: CBS, TBS, TNT and TruTV. Yep, the time has come again to find TruTV on your dial.
Can I stream March Madness for free?
Go to the NCAA’s March Madness Live site or use its March Madness Live app and you’ll be able to watch games for free. You can watch March Madness Live on iOS and Android devices along with Apple TV, Roku, Fire TV and Xbox One. The app also supports AirPlay and Chromecast.
As with most things that are free, there’s a catch. Without proving you’re a pay-TV subscriber, you get only a three-hour preview, after which point you’ll need to log in to continue watching.
What are my other streaming options?
You can use a live TV streaming service to watch March Madness. Three of the five live TV streaming services offer the four channels needed to watch every tournament game, but keep in mind that not every service carries every local network, so check each one using the links below to make sure it carries CBS in your area.

Here’s an Image of the Asteroid Everyone Was Worried About
NASA’s James Webb Space Telescope captured a glimpse of the asteroid that had a chance of impacting Earth three months ago.

It’s not every day that an asteroid causes as much buzz as 2024 YR4. At one point, the asteroid had a 3.1% chance of hitting Earth, creating plenty of headlines about its potential impact. The threat is all but gone, but now we have pictures of the once-worrisome asteroid.
The imagery was captured by NASA’s James Webb Space Telescope and posted by the European Space Agency on Wednesday. The JWST captured the asteroid with two of its cameras, including the Near-Infrared Camera and the Mid-Infrared Instrument. The former measures reflected light, while the latter shows thermal energy.
The pictures demonstrate a couple of fun facts about the asteroid. It is the smallest object ever targeted by JWST’s instruments to date, and it’s one of the smallest objects ever directly measured. Estimates initially put the asteroid at around 40 to 90 meters. The actual size turned out to be 60 meters or around 180 feet.
«These measurements indicate that this asteroid does not share properties observed in larger asteroids,» the ESA said in its blog post. «This is likely a combination of its fast spin and lack of fine-grained sand on its surface. Further research is needed, however, this is considered consistent with a surface dominated by rocks that are roughly fist-sized or larger.»
Per NASA, the asteroid will only be visible from Earth for a little longer. The asteroid’s orbit is currently taking it away from Earth, and the agency estimates that it’ll disappear from even the strongest instruments by late April or early May. It won’t be visible again until 2028 when its orbit brings it back toward Earth.
The moon, on the other hand…
The 2024 YR4 asteroid caused quite a stir when astronomers first reported it via the Minor Planet Center in December 2024. Based on the data collected on its trajectory at that point, the asteroid had a 1.3% chance of hitting Earth.
The percentage fluctuated over the next few months, reaching as high as 3.1%. After further research, the odds dropped dramatically to 0.28%. Per NASA’s Sentry tool — which monitors asteroids that may impact Earth — the threat now sits at 0.00078%.
The moon may not be so lucky. Per NASA, the odds of the asteroid impacting the moon are somewhere around 3.8%, which is even higher odds than the asteroid ever had of impacting Earth. Scientists are gathering data before the asteroid disappears, but it’s likely we won’t know more until the asteroid comes back into view in 2028.
