John Stamos to Join ER

John Stamos (of Full House and Rebecca Romjin fame) is set to join the cast of the NBC medical drama ER for its 13th season in the fall. He will be reprising his guest starring role from this season as Tony Gates, paramedic/medical sudent. This casting fuels the rumors that Stamos' current project, ABC's Jake in Progress is officially cancelled after it was pulled from the air abruptly after one episode this season. To join NBC, Stamos would have to no longer be contractually tied to ABC, and it looks as if that is the case.
