The two leading candidates to win the Republican presidential nomination will hold rallies in Huntsville on the final weekend before Tuesday's state primaries.

Florida Sen. Marco Rubio, coming off consecutive second-place finishes in the South Carolina primary and the Nevada caucus, will hold a rally at the U.S. Space & Rocket Center on Saturday.

State Rep. Will Ainsworth, co-chair of Rubio's Alabama campaign, confirmed the event Wednesday night to AL.com.

Rubio's event will take place a day before GOP frontrunner Donald Trump holds a rally near Huntsville International Airport.

Alabama voters will head to the polls for primary elections on Tuesday as part of the so-called SEC primaries.

Rubio will have a busy Saturday in Alabama. He is scheduled to take part in a candidate forum in Birmingham and attend a private fundraiser in Huntsville.

In between, he'll be meeting supporters at one of the state's most prolific locations.

The rally is scheduled for 5:30 p.m. and doors to the space center will open at 4:30.

There is no admission charge for the event but tickets are required. Click here for more information.

Rubio previously made a campaign stop in Guntersville in December.
