New Orleans Saints tight end Jimmy Graham was in the midst of a “medical episode” and was disoriented when he was arrested in the Los Angeles area and transported to a hospital, it was announced Saturday.

Graham was stopped by police on Friday night while wandering in traffic and booked on suspicion of being under the influence of a controlled substance.

The Saints announced Graham has been evaluated by team doctor John Amoss, was released from a hospital on Saturday morning and was back with the team as it prepared for a preseason game on Sunday night against the Los Angeles Chargers.

The team said Amoss determined Graham “likely” was suffering the effects of a seizure when he was apprehended on Friday night. Graham spent the night under medical supervision and testing, the team said.

“Amoss met Graham at the hospital and is overseeing his care at this time,” the Saints’ statement said.

It was not immediately clear whether the 36-year-old Graham would be available to play on Sunday.
