Arian Foster Receives Adorable 'Get Well Soon' Card From 6-Year-Old Texans Fan (PHOTOS, VIDEO)

A 6-year-old girl has caused quite a stir on Twitter, drawing an adorable "Get Well Soon" card to her favorite Houston Texans player, Arian Foster.

After the running back left Sunday's game against the Minnesota Vikings with an irregular heartbeat, Macie Dammeyer of Cypress, Texas, made the card and asked her father to tweet it to Foster. Upon seeing the tweet, Foster responded that he was feeling better and even made the card his Twitter avatar.

The card has made the rounds on Twitter and other media outlets, with local news station KHOU 11 stopping by the Dammeyer household to interview Macie and her father, Brian.

"His heart was beating so fast that I was worried," Macie told KHOU 11. "I felt sad, so I wrote the note."

Perhaps the well-wishes helped: Foster returned to practice on Wednesday and has been cleared to play in Sunday's regular season finale against the Indianapolis Colts. In a press conference covered by KHOU 11, he reacted to Macie's card.

"It just lets you know that there are people that care about you aside from how many yards you put up," Foster said. "You see something like that, and it's very genuine and it's very sincere. She didn't have anything to gain. She was just a genuine little kid."

Macie seems to be enjoying all the publicity her card has garnered, as evidenced by another tweet put out by her father.

Foster will be a key component in Sunday's matchup against Indianapolis. The Texans can clinch the top seed in the AFC and, thus, home-field advantage throughout the conference playoffs with a win against the Colts.
