Jimmy Graham was detained by police in Southern California on Friday night after experiencing a medical episode.

The Saints said team doctors believe Graham had a seizure that resulted in him becoming disoriented.

Graham was found wandering in traffic and taken into custody on suspicion of being under the influence of a controlled substance.

"New Orleans Saints tight end Jimmy Graham experienced a medical episode last evening, which resulted in him becoming disoriented," the team said in a statement Saturday. "He was taken into custody by local authorities and transported to a local hospital for evaluation for what Dr. John Amoss believes to be a likely seizure and spent the night under medical supervision and testing. Amoss [team doctor for the Saints] met Graham at the hospital and is overseeing his care at this time. He was released this morning and is with the team as they continue preparations for Sunday's game against the Los Angeles Chargers."
