"He's progressing well and we are excited to get him back out there," coach Brandon Staley said Tuesday.
Slater, however, will not be activated ahead of Saturday's AFC wild-card playoff against the Jacksonville Jaguars at TIAA Bank Field.
The Chargers placed Slater on injured reserve after he tore a left biceps tendon in a Week 3 loss to the Jaguars and later needed surgery.
Staley said Slater's status would be "day-by-day" following Saturday's game.
"He's progressing well enough to get out there on the football field and he's been working really, really hard, so I think just having him at practice is going to be great to see," Staley said.
Rookie Jamaree Salyer, a sixth-round pick from Georgia, has started 14 games in Slater's absence.
Slater, who was selected with the 13th overall pick in the the 2021 draft, earned Pro Bowl recognition as a rookie last season.
