Who is Braugher in Fantastic Four 2?

In a Variety article talking about how Forest Whitaker will star in “ER” episodes next season, the trade mentions that the actor took over the role from Andre Braugher (images):

Braugher, an NBC veteran from his days on “Homicide: Life on the Street,” was supposed to play a patient who enters the hospital with a seemingly innocent cough but suffers a stroke while waiting to be treated. He’ll be heading to the bigscreen instead, co-starring in the Fox sequel “Fantastic Four: Rise of the Silver Surfer,” which is in pre-production.

Stay tuned for which character he may be playing.
