Uncle Jesse’s moving to ER!

Following a successful guest stint this season, John Stamos is set to join the cast of NBC’s “ER” as a regular in the fall. Stamos will reprise his role as Tony Gates, a flirtatious paramedic who also is a medical student and a Gulf War veteran. He first played the character in two episodes that aired during the November sweep.

The casting is formally in second position to Stamos’ ABC comedy “Jake in Progress,” which has aired only one episode this season. Stamos is slated to make his debut as a full-time “ER” resident in the opening episode of the long-running medical drama’s upcoming 13th season.
