Alabama coach Nick Saban accepts the "Lemon Face Challenge" from 11-year-old Aubreigh Nicholas.

Nick Saban was “honored” to eat a sour lemon on camera.

Alabama’s head football coach was issued a “Lemon Face Challenge” by 11-year-old Aubreigh Nicholas on her birthday, March 28. And on Wednesday afternoon, Aubreigh’s Army’s Facebook page shared a video of Saban accepting her challenge and eating a lemon.

“Aubreigh, I’m honored to take this Lemon Face Challenge for you,” he said. “OK, here it goes.”

Saban then bites into lemon wedges, makes an aptly-named lemon face with one eye closes and both lips pursed together before quickly recovering and finishing the video message.

“Our team is so proud to be a part of Aubreigh’s Army as you continue your fight and also your efforts in helping raise awareness for DIPG,” Saban said. “I want you to know that you are in our thoughts and prayers and we are behind you 100 percent.”

The caption that accompanied Saban’s video on Aubreigh’s Army’s Facebook page read:

“What an awesome man he is!! In his busy life with family and football, he took a minute to help spread awareness about DIPG and Aubreighs Army!!”

In September, Aubreigh was diagnosed with diffuse intrinsic pontine glioma, or DIPG, which is a rare and incurable form of childhood brain cancer. But dating back to last football season, the Semmes, Ala., native has had no shortage of support during her battle, especially from Saban and the Crimson Tide football team.

Prior to the Alabama-Ole Miss game, Aubreigh and her family met with Saban on the field inside Bryant-Denny Stadium after the team stepped off the buses. Now-junior quarterback Jalen Hurts sported an Aubreigh’s Army wristband during the 66-3 win over the Rebels.

Once his face returned to its normal state, Saban closed out his message to Aubreigh with:

“God bless you, and Roll Tide.”
