“The Walking Dead” star has been diagnosed with stage 4 colon cancer

The Walking Dead star Tyrese Gibson is recovering well after being diagnosed with a stage 4 bowel cancer, according to his manager.

Gibson, who was diagnosed with colon cancer in July, had surgery last month to remove the cancer from his stomach, and was on the mend in the weeks before the news broke, his manager, Kevin Williamson, told PEOPLE on Tuesday.

“He is in good spirits,” Williamson said of the 41-year-old actor.

“He has been working on his diet and is in great shape.

We are optimistic that he will be in good shape for his upcoming return.”

Gibbs, who will return to the series in early 2018, was a finalist for the Emmy Award for Outstanding Lead Actor in a Drama Series in 2013.

The actor is one of three nominees for the show’s seventh and final season.

He has not yet spoken publicly about his diagnosis, but said recently that he had not made a decision. 

“It is a scary time,” Gibson said of his cancer diagnosis last year.

“It is hard to get used to.

But I have been through this before, and it is not something that can be brushed aside.

The people that are with me are there for me.

I am not going to let them down.”

Ginson has appeared in more than 200 episodes of the zombie drama, which has aired for 13 seasons.

He most recently appeared in Season 2 of the series as Rick Grimes, a former soldier who left the military and is a father to a son he has never met. 

Gibbers role on the show was initially limited to the role of a doctor in a hospital ward and later he was cast as an ambulance driver. 

It is unknown when Gibson will be able to return to action.

He recently returned to the set of AMC’s The Walking Bad after a year-long layoff, according the Hollywood Reporter.
