Glee Season 5 Finn Hudson recasting?

In his report, Hollywood scoop writer Perez Hilton wrote, "Finn was meant to be heavily featured in the fifth season’s already-written first two episodes." Finn was supposed to be studying to become a teacher after having realized he has enjoyed being New Directions' temp coach in Mr Schu's absence.

Lea Michele, who plays Finn's love interest Rachel Berry is understood to be under contract for two more Glee seasons. Rachel was believed to be ready to take Finn back after he "defended her hounour" against her masquerading sex worker boyfriend.

Fears of recasting Finn Hudson to continue the fictional couple's storyline are being discussed on social media channel and forum sites. However, no recasting has been confirmed.
