The coach returned to work Tuesday after being admitted to the hospital on Monday. NFL Network Insider Ian Rapoport reported that Arians underwent testing for symptoms related to chest pains. He was released from the hospital Monday night.
Arians is expected to be on the practice field Wednesday.
Arians was hospitalized earlier this year after dealing with symptoms associated with Diverticulitis, a condition which affects the digestive tract.
That the 64-year-old will be well enough to coach Sunday is great news for the Cardinals as they attempt to buoy fading playoff hopes.
