Fielding suffered a groin injury in the Championship draw at Middlesbrough at the start of October.
He made his comeback last week, playing the full 90 minutes as the Rams' Under-21 side lost 2-1 to Nottingham Forest.
And the 24-year-old was on the bench for the first team on Saturday as Derby lost 3-0 to league leaders Crystal Palace at Selhurst Park.
Fielding will start again for the Under-21s when they face Barnsley at Derby's Moor Farm training ground.
