McCluster (hamstring) is listed as questionable for Thursday's game against the Broncos, Michael Gehlken of the San Diego-Union Tribune reports.
Though McCluster could in time factor in as a pass-catching threat out of the San Diego backfield with Danny Woodhead not available-- particularly given his familiarity with offensive coordinator Ken Whisenhunt's system-- thus far he's done more as a returner than as a running back over his first three games as a Charger.
