The adorable little girl who got a TD ball from Carolina Panthers RB Jonathan Stewart yesterday drove 100 miles with her family to attend the game ... and says she'll NEVER sell it, EVER!!
The lucky fan is 8-year-old Isabella -- who was at the game with her mom, dad and brother who are all Panthers super fans ... and usually sit in the nosebleed section when they attend games.
But Isabella's father Kelly tells TMZ Sports he splurged for the playoff game -- dropping more than $2,500 for the killer endzone seats because he felt something special was going to happen.
