The doctor will be in on Criminal Minds for at least two more seasons.

In casting news first broken by Deadline, Matthew Gray Gubler has signed a new contract with this CBS drama that will keep Dr. Spencer Reid for another two years. The character, a fan favorite, graduated college at 12 and possesses an IQ of 187.

Criminal Minds, of course, is going through a mini shake-up. Paget Brewster exited following Season 7 and former Big Love star Jeanne Tripplehorn has been brought in to essentially replace her.

She'll debut on the Season 8 premiere this fall.
