Update (3 p.m.): NFL Network's Mike Garafolo reported Bruce Arians attended Cardinals practice Wednesday afternoon but left about 30 minutes in, as planned. Garafolo said Arians wanted to take in at least a portion of the practice.
Arizona Cardinals coach Bruce Arians was released from a San Diego hospital Wednesday morning after being admitted Tuesday evening for stomach pain.
Mark Dalton, Cardinals vice president of media relations, reported Wednesday morning that Arians has rejoined the team and is resting at the team's hotel.
Just before noon Cardinals coach addressed the media Wednesday and said he has been diagnosed with diverticulitis and will need to change his diet. "I'm too old not to listen to doctors anymore," he said.
Arians, 63, said he will rejoin the team for practice Wednesday afternoon.
BA: "I'll go to practice today and see how it goes."

Arians left the Cardinals' Tuesday night joint practice with the Chargers in San Diego early after complaining of stomach pain to team medical staff. He was taken to a nearby hospital where he remained overnight for evaluation.
"We're very relieved," Cardinals quarterback Carson Palmer said Wednesday. "The one thing our guys in that locker room know is he's as tough as anyone in that locker room.
"I'm sure he was saying, 'I'm good, I'm good, I'm fine,' and trying to jump out of the bed and get to the field. But just to know he's back and resting is great news."
Arians has overcome health problems in the past. He was diagnosed with prostate cancer in 2007, but underwent surgery and has been cancer-free ever since.
The Cardinals are in San Diego this week for a pair of joint practices with the Chargers before they face each other in Friday's preseason game at Qualcomm Stadium.
Palmer said the team said a quick prayer for Arians after they heard the news Tuesday night before carrying on with business as usual during practice.
"If there's a reason for that, it's because you know that's what he wanted us to do," he said.
