Long made just one of his three field-goal attempts and his lone extra-point attempt in Sunday's 13-10 loss to the Lions.
The Chargers' multi-season kicking nightmares resurfaced Sunday, as Long's second-half misses from 39 and 41 yards ultimately cost the team the win. Starting kicker Michael Badgley is expected to be healthy for Week 3 following two straight absences due to a groin injury, so it's likely Long will slide back to his role as punter for the foreseeable future.
