12:18 PM PT -- Sources with direct knowledge tell TMZ Sports ... Michael and his camp have actually not heard from Shaquem's agent to discuss the selling of rights for his movie and no talks have been had at all.

Shaquem Griffin says interest in a biopic about his life has recently exploded ... so much so, he tells TMZ Sports Michael B. Jordan has shown interest in acquiring it!!

The former NFL star -- who inspiringly made it to the league despite having his left hand amputated when he was just 4 years old -- has been working on a movie about his life journey for over two years.

He told us out at Super Bowl week in Las Vegas that, initially, he wanted to get the flick out ASAP. But, he said as more and more people have become aware of the project, he's seen plenty eager to get their hands on it ... including Adonis Creed himself.

He explained ... his agent has been in talks with Jordan's Outlier Society production company -- and he's confident even more are going to come forward as the script gets closer and closer to being done.

"Something special is finna happen," Griffin said.

Unclear if MBJ would have his eyes on the starring role ... but if he did, Griffin would clearly endorse it, even if they would then need to add his limb difference via CGI.

Griffin has now been out of the NFL since the 2021 season ... but he's stayed busy in retirement. In addition to working on his movie, his twin brother told us back in 2022 he's become a damn good motivational speaker as well.
