The Chargers signed Maye from the practice squad to the active roster Saturday ahead of Sunday's game against the Broncos.
With Elijah Molden (hamstring) out and RJ Mickens (shoulder) questionable, Maye is set to be the primary backup at free safety for Sunday's game. If he suits up, Week 18 will be the defensive back's first game of the season, and he will likely fill a special-teams role if Mickens is inactive.
