Houston Texans defensive end J.J. Watt replaced a young fan's homemade No. 99 jersey with a real one.
Malinda Ross, a teacher at Moore Elementary School in Houston, tweeted a photo last week of herself and two of her students sporting Watt jerseys to celebrate the 99th day of school.
Watt noticed one of the students - a boy named Brock - had created his own jersey by pinning two nines to a shirt, and offered to send him an authentic one.
On Wednesday, Watt personally delivered two new jerseys to Brock.
Watt also signed the back of one of the jerseys, writing, "Brock, thank you for the support! Dream big, work hard!"
