Lambert-Smith (hamstring) is listed as questionable for Sunday's game against the Steelers, Eric Smith of the Chargers' official site reports.
Lambert-Smith appeared on the injury report Thursday with a hamstring issue, and he managed to log only limited participation in both Thursday's and Friday's practices. The rookie fifth-rounder has logged only four targets, resulting in one reception for one yard, through his first six career games. If the wide receiver is unable to go Sunday, Derius Davis may be in line to receive a few offensive snaps.
