Eli Manning is the newest member of Death Row ... and if you don't believe it, check out his new birthday chain -- courtesy of Snoop Dogg!!!
Snoop was the special guest during the third quarter of the Browns vs. Steelers "Manning Cast" on ESPN2 Monday night ... which just so happened to be Eli's 41st birthday.
And, D-O-Double-G was ready for the occasion ... whipping out a "Death Row Records" gold and diamond chain for the birthday boy -- and Eli's reaction is priceless!!
"Eli, I would like to present to you this Death Row chain for being so hip-hop!
