NFL's Daniel Fells Emotional Return Home ... After 3 Weeks In Hospital (Video)

This one might make you tear up ... footage of NY Giants tight end Daniel Fells greeted by his kids the moment he returned home from a horrible 3 week hospital stay .. and they're PUMPED!!!

Fells nearly had his foot amputated due to an aggressive MRSA infection -- for which he underwent 7 surgeries, with at least 2 more surgeries expected.

His season -- and most likely his NFL career -- is over ... but he seemed to forget about all of that when he was greeted by his adorable kids on Tuesday.
