NFL star grants Christmas wish to boy with heart condition. The child's reaction is tear-jerking.

A 10-year-old boy recently diagnosed with a life-threatening heart condition saw his Christmas wish come true, thanks to NFL star Cam Newton.

The Carolina Panthers quarterback paid a visit to Taylor Deckard at an Atlanta hospital Tuesday, WSOC-TV reported.

The boy, who is set to undergo surgery for advanced pulmonary hypertension, a life-threatening condition, excitedly greeted his football idol while sporting the athlete's jersey from Newton's alma mater, Auburn University.

"What's going on, buddy? How are you doing?" Newton asked Deckard as he walked into his hospital room. The boy responded by hopping out of bed, wrapping his arms around the famous football player and refusing to let go.
