Los Angeles: Actor Max Adler is returning for the final season of musical TV series `Glee`.
The 28-year-old actor will reprise the role of Dave Karofsky in at least four of the remaining 13 episodes, reportedly.
It has also been reported that Karofsky will appear as the boyfriend of Blaine (Darren Criss).
Blaine and Kurt (Chris Colfer) were in a relationship when the fifth season concluded earlier this year, but creator Ryan Murphy has confirmed that the final season will feature a time jump.
Adler last appeared in `Glee` in the 17th episode of last season, when he featured in a dream sequence.
Karofsky originally bullied Kurt, but was later revealed to be gay and was seen struggling with his sexuality. `Glee`s sixth and final season, consisting of 13 uninterrupted episodes, is expected to air next year.
