On Saturday, quarterbacks Derek Carr of the Oakland Raiders and Andrew Luck of the Indianapolis Colts will go head-to-head for the first time as professional football players.

This isn't the first time they'll square off on the same field, though.

These two up-and-coming passers played against each other in high school. Carr was asked to recall what he could about that matchup on Tuesday.

It sounds like Luck's performance in that game left a lasting impression on his Week 16 opponent.

The high school clash between Carr and Luck was a Texas Class 5A Region III semifinals, according to The Mercury News, and it was played on Dec. 1, 2007. In that game, Carr led Clements High (Sugar Land, Texas) to a 31-27 victory over Luck and Houston's Stratford High.

"You could tell, obviously, that he was going to be a really, really good player," Luck said of Carr, per The Mercury News. "I think he’s more athletic than people give him credit for. He runs around and makes some great players. He does a great job taking care of the ball. I’m a big fan."

Carr and Luck are very close in several key statistical categories this season:

63.5 (17th) 63.7 (16th)3,705 (9th) 3,631 (11th)25 (t-7th) 27 (5th)6 1095.2 (12th) 97.1 (8th)

The biggest difference between these two signal callers is their team's respective records. Carr's Raiders are 11-3 and have already clinched a playoff spot, while Luck's Colts are 7-7 and still fighting for the playoff lives.

Carr and Luck are both under the age of 28 and have the potential to be the next Peyton Manning/Tom Brady. We'll see which quarterback comes out on top in Week 16.
