Brothers & Sisters

One of the new characters on Brothers & Sisters has been cast.

Denzel Whitaker will play a lab partner for Justin, as Dave Annable's character will be enrolled in medical school when the ABC series returns in September. 

The young actor starred in the film The Great Debaters and has appeared on ER and CSI. His character of Carter has been billed as a Doogie Howser-like prodigy who will inspire Justin to question his priorities in life.

Whitaker premieres in the third episode of the season.
