The San Francisco 49ers announced Thursday they have traded Ken Dorsey and an undisclosed seventh-round selection in the 2007 draft to the Cleveland Browns for QB Trent Dilfer.

“Trent was a player we had interest in last season,” Head Coach Mike Nolan said. “We were looking for a veteran quarterback with experience that could help mentor Alex Smith. Trent fits the bill on both counts and we are excited to have him with the 49ers.”
