According to The Hollywood Reporter, Kennedy will play a graduate psychology student at the local university. His character will form some sort of bond with Jennifer Love Hewitt's Melinda when the drama returns for its fourth season this fall.
Kennedy's character will be an almost one-for-one replacement for Jay Mohr's Professor Rick Payne. Mohr's character will reportedly appear in several episodes at the start of the season before being smoothly written off.
Mohr, meanwhile, will be starring in his own CBS sitcom, the Wednesday comedy "Project Gary."
