Similar to a Battle Royal, a wrestler is eliminated when thrown over the top rope, with both feet touching the floor. A referee, who is seated at ringside, must see an elimination in order for it to be valid. A wrestler who is eliminated without a referee noticing may sometimes sneak back into the match. For example, Stone Cold Steve Austin was eliminated during the 1997 event, but he re-entered without the referees' seeing and eventually won the match. A wrestler who leaves the ring without going over the top rope is not eliminated from the match. During the 1999 Rumble match, both Vince McMahon and Steve Austin left the ring, only to return later in the match. In the 1994 match, the last two wrestlers, Bret Hart and Lex Luger were declared co-winners when it was decided that both of their feet touched the floor at the same time. A similar situation occurred in the 2005 match, however the match was restarted after Batista and John Cena eliminated each other at the same time. Batista eliminated Cena afterwards to win the match.
