The visitors, meanwhile, will be hoping to continue their fine spell of form after putting together a six-game unbeaten run in all competitions.
Match preview
Derby experienced FA Cup disappointment in their most recent outing after they gave up a slender lead to lose 3-1 to fourth-tier Crewe Alexandra in their first-round replay at Pride Park.
While an early cup exit will certainly frustrate Paul Warne, his main priority this season is to win promotion and end Derby's two-season stay in League One.
Having collected 27 points from 16 matches, the Rams are currently sitting in seventh place with goals scored keeping them outside the top six.
They have enjoyed considerable success in their last two league matches, sweeping past Northampton Town 4-0, before claiming a commanding 3-0 victory over sixth-placed Barnsley.
With both of those wins taking place at Pride Park, Derby are now unbeaten in six home league games since losing to Oxford United in mid-August.
Bristol Rovers, meanwhile, have enjoyed a fine run of form since interim boss Andy Mangan took over the reins from Joey Barton, who was sacked following a 1-1 draw against Stevenage on October 24.
Impressively, the caretaker manager has seen his side put together a five-game unbeaten run, which began with home victories over Northampton Town and Whitby Town in the league and FA Cup respectively.
After playing out a 1-1 draw with Reading, the Gas returned to winning ways in their last two outings, beating Carlisle United in the league before getting the better of Newport County in the EFL Trophy.
They will be hoping to extend their unbeaten run with another victory on Saturday, as the 10th-placed side look to close the four-point gap to the playoffs.
Having failed to beat Derby in their last six league meeting, a victory at Pride Park would represent their first league win over the Rams since April 1986.
