Hopkins, a wide receiver for the Houston Texans, said Barnes reminded him of his own daughter. He pledged to give his $29,000 playoff check to Barnes' family.
"I will be playing in your honor, Jazmine," he wrote on Twitter.
On January 3, basketball star Shaquille O'Neal reportedly dropped off a check, along with Houston police officer Kenneth Miles, to help cover the funeral costs.
Many others have donated to a GoFundMe page started by Barnes' father, Chris Cevilla.
