Arizona Cardinals coach Bruce Arians has been hospitalized after complaining of stomach pain.

A Cardinals spokesman says that after Arians arrived for the team’s practice with the San Diego Chargers at Qualcomm Stadium in San Diego, he told staff he wasn’t feeling well. Arians is undergoing tests, and an update is expected later today.

The 63-year-old is a two-time NFL coach of the year and is in his fourth season with the Cardinals.
