Two Elite 8 games in the NCAA men's basketball tournament are going down tonight - find out how you can watch them both live online for free.

No. 1 Oregon will face off against No. 2 Oklahoma in the first Elite 8 game of the 2016 NCAA tournament. The tip off is at 6:09 p.m. ET, and the game will be airing live on CBS at that time. It's going to be a big game for both teams as this is their first Elite 8 presence in quite some time.

Oregon has not been in the Elite 8 since 2007, while Oklahoma hasn't been in since 2009. It will be a big deal for whichever team wins, since Oregon hasn't made the Final 4 since 1939 (where they would go on to win the Championship) while Oklahoma hasn't been in since 2002.

The next game is slated to begin at 8:49 p.m. ET, also airing on CBS. No. 1 Kansas is playing No. 2 Villanova for a shot in the Final 4. Both schools have won the NCAA tournament before - Kansas won in 1952, 1988 and 2008 while Villanova won in 1985. Both have had a major presence in the tournament for decades.

Tomorrow, No. 1 Virginia will play No. 10 Syracuse while No. 1 North Carolina will play No. 6 Notre Dame.
