Coach Anthony Lynn liked the way both players practiced this week but said their snaps will be limited.
The Chargers also promoted wide receiver Jalen Guyton from the practice squad on Saturday. In corresponding moves, defensive tackle T.Y. McGill and safety Shalom Luani were waived while wide receiver Geremy Davis was placed on injured reserve.
