"Do I think I can play tackle?" Long said last week. "No doubt. Will I play tackle? No idea. I am a right guard."
NFL Media's Daniel Jeremiah noted in June that many in the NFL believed Long would end up starting the season at right tackle because a blocker of his caliber is much more valuable on the outside than at guard.
Sunday's roster shakeup could turn belief into reality. Vladimir Ducasse or Omameh could take over the guard spot if Long moves to tackle.
