SAN DIEGO (AP) Arizona Cardinals coach Bruce Arians was released from the hospital on Wednesday after an overnight stay and pronounced the stomach problem that sent him there ''no big deal.''
He planned to heed doctors' advice to take it easy, he said before the team held another joint practice with the San Diego Chargers on Wednesday afternoon.
''I'm too old not to listen to doctors anymore,'' he said. ''I have a tendency to push it, but we'll go out today and see how long we stay. It's nothing serious.''
Arians left Wednesday's practice after about a half hour.
The 63-year-old coach was taken to the hospital Tuesday night after complaining of stomach pain as the Cardinals prepared for a joint practice with the Chargers at Qualcomm Stadium.
''Just had a bunch of stomach pain and doubled over, which is what it does to you,'' he said. ''I thought it was a kidney stone at first.''
Arians said he had been diagnosed with diverticulitis after a recent colonoscopy.
''It's a good thing I do those every two years,'' he said.
He said doctors adjusted his diet a little bit although he had already been on a strict diet anyway.
''Change diet a little bit, basically that's it,'' Arians said. ''Drink a lot of water. ... No big deal.''
Cornerback Patrick Peterson said the team practiced without its coach without difficulty after the players were told that Arians' ailment was nothing serious.
''It wasn't tough because we know coach is a trooper,'' Peterson said. ''He's strong and he wouldn't want us showing any pity on the practice field. We had the same practice intensity.''
The Cardinals held the two joint practices with the Chargers in advance of the teams' preseason game in San Diego on Friday night.
The two-time NFL coach of the year is entering his fourth season with the Cardinals, compiling a 34-14 record.
The Cardinals will have Saturday off before beginning their final week of training camp on Sunday at University of Phoenix Stadium in Glendale, Arizona.
