Arizona Cardinals coach Bruce Arians became ill during the team's practice with the Chargers in San Diego on Tuesday night, and he was taken to a hospital by ambulance.
The Cardinals announced that Arians experienced stomach pain. He underwent tests and was expected to stay overnight in the hospital. A team source told AZcentral.com, "He'll be fine."
AZCentral.com reported that Arians wasn't feeling well ahead of the practice at Qualcomm Stadium and that team physician Wayne Kuhl accompanied him to the hospital before later returning to the joint practice.
"It was definitely different, we missed him out there today," tight end Troy Niklas told AZCentral.com.
Arians, 63, is entering his fourth season as the Cardinals' coach. His squad has improved each year: 10-6 in 2013, 11-5 before a wild-card playoff loss in 2014, then 13-3 with a trip the NFC Championship Game in 2015.
Before moving to Arizona, Arians was the offensive coordinator of the Pittsburgh Steelers (2007-11) and the Indianapolis Colts (2012). He became the Colts' interim head coach on Oct. 1, 2012, when Chuck Pagano stepped away to deal with leukemia, and Arians guided Indianapolis to a 9-3 record. He was selected NFL Coach of the Year that season, then again in 2014.
The Cardinals are due to scrimmage against the Chargers again Wednesday afternoon ahead of a Friday night preseason game in San Diego. Arizona lost 31-10 to the visiting Oakland Raiders last Friday.
