Snoop Dogg is a man of his word -- the rap legend just held up his birthday promise and delivered a "Death Row" chain to Eli Manning for his birthday ... and the QB is stoked!!
Remember, the hip hop legend appeared on ESPN 2's "Manning Cast" with Peyton and Eli earlier this month ... and revealed the gift to the ex-Giants QB for his 41st birthday.
But Snoop wasn't just blowing smoke -- the 2-time Super Bowl champ had it delivered to him on Monday .
