Jackson (hamstring) is listed as questionable for Sunday's game against the Rams, Eric Smith of the Chargers' official site reports.
A hamstring injury prevented Jackson from playing in the Chargers' two games prior to the Week 7 bye. He was a limited participant in all three practices during Week 8 prep, but if he cannot play, then Rodney Shelley (hamstring) and Tarheeb Still would be candidates to start opposite Cam Hart at outside cornerback.
