Here's Eli Manning clearly devastated he ain't playing football any -- AHHH JUST KIDDING!! ELI'S HITTING THE LINKS WITH HIS BIG BRO AND OBVIOUSLY LOVING RETIREMENT!!!
The ex-NY Giants QB -- who just officially called it an NFL career on Jan. 24 -- hit the pro-am at Pebble Beach on Thursday ... and he sure didn't look like a guy who's missing getting hit for a living.
Eli and Peyton were part of a foursome alongside pros Kevin Chappell and Luke Donald ... and the Manning bros actually played pretty well.
