More than 200 people attended a bone marrow drive on Tuesday to help save the young boy's life.
Recently Bryan received a transplant from his brother, but it did not take.
On Tuesday, at the drive, people had the inside of their cheeks swabbed.
Those swabs were then sent out for testing to find a match.
Bryan has gone through remission twice, but his family says he's now fighting an even more aggressive cancer.
They say Bryan is currently in critical condition as he awaits a transplant.
He loves playing all sports and his stuffed animal is named Borris.
He's also a big fan of the WWE and hopes he can one day meet wrestler John Cena.
The family has set up a GoFundMe account to help with expenses.
