This is sad news. I thought that Teddy's coming out storyline in the third season of 90210 was a really strong point for his character. Unfortunately,
TV Line has confirmed that Trevor Donovan will not be a regular cast member for season 4 of 90210.
Donovan will return as a recurring guest star in season 4 and will appear in approximately five episodes.
Overall, 90210 is going through a period of change. Showrunner Rebecca Sinclair has departed and two new showrunners - Patti Carr and Lara Olsen from Life Unexpected - have been hired to transition the show to its fourth season, which will see the 90210 kids going off to college. Its last two parental characters - Lori Loughlin and Ryan Eggold - are also departing.
There's no telling whether there will be more cast changes for next season of 90210. In our recent recap of season 3, we mentioned that AnnaLynne McCord had said all of the cast members would not be returning and it looks like Trevor Donovan is among them. We don't yet know if anyone else will be leaving, but we should know more details as the cast and crew head back to work in the coming months.
