Bruce Arians tweets he's 'doing good' after hospital stay

Arizona Cardinals coach Bruce Arians was back at the team's facility on Tuesday and tweeted that he was "doing good" and "back with the guys."

Mark Dalton, the Cardinals' vice president of media relations, tweeted a picture of Arians at the facility Tuesday and said the coach is expected to lead practice Wednesday and coach the team Sunday when it plays a road game against theAtlanta Falcons.

Arians was released from the hospital Monday night and returned home after feeling ill. Arians was taken to the hospital because of chest pains, sources close to the situation told ESPN's Adam Schefter.

The Cardinals said in a statement Monday that Arians experienced discomfort after he and the team returned from Minnesota, where Arizona lost 30-24 on Sunday.

In August, Arians was rushed to a San Diego hospital before a Cardinals preseason game against the San Diego Chargers, thinking he had a kidney stone. The Cardinals said Arians was suffering from complications from diverticulitis, an inflammation in the colon.

He spent the night in the hospital and was released the next morning.

Arians' health has been an issue throughout his career.

He gained 33 pounds during his first season in Arizona but lost about 15 in the first two months after the season. He began walking before practices during the 2013 season but hasn't been seen doing that in a couple of seasons.

Before his time with the Cardinals, Arians was hospitalized before an Indianapolis Colts wild-card game against the Baltimore Ravens in 2013 because of an ear infection.

He also underwent surgery for prostate cancer in 2007 while with the Pittsburgh Steelers.

When he was the head coach at Temple, Arians said he was hospitalized for migraines, sometimes up to twice a week. He said the migraines stopped as soon as he was fired from Temple in 1988.
