Drew Lock returned to a full practice Thursday

Giants quarterback Drew Lock (heel/elbow) returned to full participation in Thursday's practice. Lock was limited Wednesday.

The Giants plan to start Lock on Sunday against the Giants.

Lock started two games for the Giants before sitting out last weekend with his injuries. Tommy DeVito started in his place but was diagnosed with a concussion in the team's loss to the Saints. Tim Boyle finished the game.

Lock went 42-of-81 for 405 yards and two interceptions in his two previous starts.

The Giants had six other changes to their lengthy injury report: Safety Dane Belton (knee), defensive tackle Cory Durden (shoulder), tight end Chris Manhertz (ankle), wide receiver Malik Nabers (knee/foot) and wide receiver Wan'Dale Robinson (shoulder) were full participants a day after being limited. Cornerback Cor'Dale Flott, who had a limited practice Wednesday with a quad injury, now has a finger injury and again was limited.

Outside linebacker Brian Burns (ankle/neck), linebacker Patrick Johnson (knee), inside linebacker Bobby Okereke (back), offensive guard Aaron Stinnie (concussion) and cornerback Greg Stroman Jr. (shoulder/shin) remained non-participants.
