In this Nov. 22, 1986, file photo, Mike Tyson, right, delivers a blow to Trevor Berbick during a boxing bout in Las Vegas. Tyson hasn’t announced any plans to return to the ring, though he did suggest on an Instagram post he might make himself available for 3 or 4-round exhibitions if the price was right. And already some people in Australia are talking about offering him $1 million to fight an exhibition against a rugby star or two. (AP Photo/Douglas C. Pizac, File)
