Deion Sanders is feeling "complete" on his 55th birthday ... 'cause the NFL legend hilariously got hooked up with some new fake toes to replace the appendages he had amputated this year!!
The Jackson State football HC got the gag gift from his pal, Sam, on Monday ... and shared the whole gift-giving on his Instagram story.
The Hall of Famer was chilling in the JSU facility when Sam handed over some massive rubber feet ... which featured veins to make 'em look real.
Sanders -- who had two toes cut off earlier this year -- didn't get pissed about the personal jab ... instead, he laughed it off and said, "I like that!!
"Y'all got jokes!! Thank you. I really feel complete now."
But, Sam better watch his back ... Sanders clapped back, "I'mma kick some butt today, starting off with you Sam."
As for the color of the feet -- Sam says Deion had previously joked he wanted two white prosthetic toes ... so he figured he'd do his part.
As we previously reported, Sanders had to get surgery on his left foot due to a longtime injury he suffered during his 14-year NFL career.
He got the procedure done last fall, but suffered complications and had to go under the knife eight more times ... including removing two toes in March.
Sanders has been in good spirits since -- from dancing to working out and celebrating his 55th birthday on Aug. 9.
Happy (belated) bday, Primetime!
