Jones (hand) is questionable to return to Thursday's preseason opener against the Titans, Jennifer Lee Chan of NBC Sports Bay Area reports.
Jones exited the contest in the first quarter with an apparent hand injury. Even if the cornerback is capable of returning to the game, the team will likely hold him out as a precaution. Jones is competing to take over outside cornerback snaps across from Deommodore Lenoir, but Renardo Green is still the presumed favorite to enter the season with a starting role.
