Richards, who missed the 1-0 win at Oxford last weekend with a knock, gives manager Paul Cook another option up front. He will be hoping for a recall along with the likes of Armand Gnanduillet, Sam Togwell, Jamie Devitt, Ryan Edwards and Gary McSheffrey while fit-again club captain Ian Evatt still awaits his debut.
Ahead of the Saturday lunchtime kick-off, Cook said: "Last time we went into a big local game, it was against Rotherham. We let the supporters down and we let ourselves down. But we've evolved as a club since then and this is our next big test in terms of local rivalry.
"We know what it means to our supporters but we also know what it means to them to be top of the league and get promoted."
