Amazing news ... Central Michigan quarterback John Keller has pulled through after being shot in the chest last month -- and he's now heading home from the hospital!!
The 20-year-old athlete's chances of making it to this point appeared VERY grim less than 4 weeks ago ... after his family said he was "fighting for his life" after being struck by gunfire at a party in Mount Pleasant, Michigan.
But Keller -- who required a ventilator and a lengthy stay in the ICU as part of his recovery process -- has finally been discharged, and he couldn't be happier about it!!
"Very thankful to be heading home today," Keller wrote on his Twitter page on Friday.
