Bryan Cranston is setting off alarm bells with his post asking for prayers for his buddy Bob Odenkirk.
The Better Call Saul actor was rushed to the hospital on Tuesday after he collapsed on set while filming the prequel.
Odenkirk -- who is only 58 years old -- was filming the popular sixth and final season in New Mexico when the incident occurred.
A lot of questions surround his condition, but Cranston is adding to fans' worry that it might be more serious than expected.
The Breaking Bad actor shared a post on Wednesday, giving a grim update and asking for prayers.
“Today I woke up to news that has made me anxious all morning,” Cranston said on Instagram, sharing a photo of himself with Odenkirk.
“My friend, Bob Odenkirk collapsed last night on the set of Better Call Saul. He is in the hospital in Albuquerque and receiving the medical attention he needs but his condition is not known to the public as yet," he continued.
Ending his emotional message, Cranston asked his 3.1 million followers to "please take a moment in your day today to think about him and send positive thoughts and prayers his way, thank you.”
Cranston doesn't often post about his personal life on social media. His dedication to Odenkirk's condition is making fans of the star wary.
Several commented with prayers for the actor, with many going to a dark place.
"I almost got a heart attack. Don't slip Jimmy. We need you," one person wrote, referencing Odenkirk's Better Call Saul character Jimmy McGill -- better known as Saul Goodman.
"Really hopes he gets better..." added another. "Jesse we need to save Saul," posted a third.
Following his collapse, Odenkirk was taken to a nearby hospital in an ambulance.
According to reports, the actor is still getting medical attention and information is not yet known as to his condition.
