I checked and the character of "Matt Rutherford" is not listed in any episodes of season 2. Also it says he has a movie coming. Either he was released from Glee to pursue a movie career, or Glee ousted him from the show, thinking that nobody would notice.
Matt Rutherford did 13 shows http://www.imdb.com/character/ch0161769/
Played by (Dijon Talton)
You might know him as Matt Rutherford, Glee's first season resident non-talker alongside Mike Chang. In reality, he's Dijon Talton, an actor and dancer who is no longer on the show. Sorry, fans! There is some good news though: Dijon's got a new movie coming out and there's a trailer!Called I Will Follow, it's a new indie drama that doesn't feature much singing or dancing. Too bad, Dijon. You'll be missed on Glee!
