Brett Favre says he’s down to donate his brain following his death so it can be used for CTE research … though he tells TMZ Sports he’s sure hopeful that’s a decision he and his family won’t have to make for a LONG time.

Favre infamously dealt with head injuries throughout his 20-year NFL career … and when we asked him this week if he’d consider giving his cerebrum up to scientists following his passing so it can be studied, he said he wouldn’t mind.

Of course, the 55-year-old Hall of Famer told us he’d prefer if that choice came far later than sooner.

So much so, Leigh Steinberg is actually going to honor him with a humanitarian award at a Super Bowl party later Saturday in New Orleans, in part, due to his work on the matter.

Favre’s become even more invested in it all recently, as he reiterated to us once again he believes it played a part in his Parkinson’s diagnosis. And, he told us if he were able to ultimately help find a cure for everything, “that would be the greatest accomplishment that I’m a part of.”

A$AP Relli was the aggressor in his heated exchange with A$AP Rocky and Relli told Rocky to squeeze the trigger on the fake gun he was holding … at least according to A$AP Twelvyy.

Twelvyy took the stand Friday in the criminal assault trial for Rocky, whose defense team is finally presenting its case.

Rocky’s attorney, Joe Tacopina, claims the gun Rocky used to shoot at Relli was a starter pistol firing blanks …  and Twelvyy says Relli knew it wasn’t a deadly weapon.

As we reported … Relli claims Rocky shot at him and the bullets grazed his knuckles … and last week he compared his alleged wounds to Donald Trump‘s ear injury from the assassination attempt.
