Cardinals coach Bruce Arians taken to hospital prior to practice

— -- SAN DIEGO -- Arizona Cardinals coach Bruce Arians was taken to a San Diego-area hospital by ambulance before Tuesday night's practice against the? Chargers?at Qualcomm Stadium.

According to a Cardinals spokesman's tweet, Arians alerted the team's medical staff that he wasn't feeling well and was "experiencing stomach pain." After being evaluated by medical staff at the stadium, Arians was transported to the hospital before the start of the 9 p.m. ET practice.

After undergoing testing, Arians will remain hospitalized overnight, and his condition will be updated Wednesday.

The two teams huddled together before the start of practice and appeared to be addressed by Chargers coach Mike McCoy.

Arizona is in San Diego for the week to practice with the Chargers ahead of Friday's preseason matchup.

A two-time coach-of-the-year winner, the 63-year-old Arians is entering his fourth year as the Cardinals' head coach.

Arians has a history of health issues.

In 2013, as the Indianapolis Colts' offensive coordinator, he was hospitalized before the Colts' wild-card game against the Baltimore Ravens and was unable to coach in the game. A source said at the time that Arians had an inner-ear infection, and the team said doctors kept him in the hospital while they worked to stabilize his blood pressure.

He also was diagnosed with prostate cancer in 2007 and had surgery. He has been cancer-free ever since.

Arians has said that when he was the head coach at Temple University from 1983 to 1988, he used to get migraines that would land him in the hospital.

After practice, Arians was on the minds of his players.

"He's going to be fine," said Arizona wide receiver Larry Fitzgerald, as he ran off the field. "We got the toughest coach in the business."

Cardinals defensive back Tyrann Mathieu took to Twitter to extend his best wishes to Arians.

"It's scary; anytime he can't be out here at practice where you know he wants to be, it's difficult," Cardinals quarterback Drew Stanton said. "Our prayers are with him, and hopefully he'll be back out here tomorrow.

"From what I had heard, he kind of fought tooth and nail to go in the hospital but finally made a decision that's probably in his best interest. That's more important right now."

Arizona general manager Steve Keim walked past reporters without answering questions about Arians. The Cardinals have media availability at 2 p.m. ET, when quarterback Carson Palmer is scheduled to hold a news conference.
