Saints coach Dennis Allen says he expects tight end Jimmy Graham to return this week to practice following what team officials have described as a “medical episode” that led police in the Los Angeles area to arrest the veteran player and take him to a hospital. Saints team physician Dr. John Amoss has said Graham likely had a seizure and was disoriented when he was picked up by authorities in Orange County on Friday night. The Saints were in California last week for joint practices with the Los Angeles Chargers in advance of New Orleans’ 22-17 victory in both teams’ second preseason game on Sunday night. Graham did not play in the game.
