Stark issued Rooney with a straight red for kicking out as England played out a 2-2 draw in Montenegro in their final competitive game before the finals and, given his status as Fabio Capello's star player, there are concerns that it could severely hamper the country's chances.
UEFA is likely to make a ruling on the length of the suspension next month, and Stark feels it is possible that Rooney's reaction will spare him an extension to the obligatory one-match ban.
