(Tukwila, WA)  --  Seattle Sounders' Clint Dempsey may face suspension after ripping a ref's notebook in an Open Cup meltdown in their loss to the Portland Timbers Tuesday.  After receiving a yellow card, Dempsey grabbed what looked like the referee's notebook and threw it to the ground.  He then picked it up and tore it, flinging the pieces back to the ground.  He faces a ban of up to three months for referee abuse and "assault" according to the language of the rules, which includes "damaging the referee's uniform or personal property."
