1:45 PM PT -- We've spoken with a rep for Grey Flannel Auctions who tells us they've done their homework authenticating the jersey. They say unique features of the jersey -- rips, stitching pattern, etc. -- have been matched with high-quality photographs from the game.
"We believe photos show this is the same jersey," GFA says.
8:45 AM PT -- Troy Aikman says the jersey is not authentic. The auction house believes it is. We are going to make some calls and try to clear it up.
Start saving up, Cowboys fans ... 'cause Troy Aikman's GAME-WORN Super Bowl XXVII jersey is hitting the auction block ... and it ain't gonna come cheap!!
Aikman's threads -- which he wore during his 4-touchdown MVP performance against the Buffalo Bills -- have remained in original condition (unwashed) since the 1993 game.
