Frecklington suffered a glute injury in last weekend's 4-3 win at Gillingham and missed the midweek trip to Sheffield United, but boss Steve Evans has rated him 90 per cent fit.
Defender Kari Arnason sustained a knock at Bramall Lane but had to play on as the Millers, who lost for the first time since New Year's Day, had made all of their substitutions and he will be checked over.
Mark Bradley (knee) will miss the rest of the season as Evans' men aim to keep their impressive record against the Bantams going, having won the last six meetings.
Bradford pair James Hanson and Nathan Doyle remain big concerns for manager Phil Parkinson ahead of Friday's game.
Striker Hanson has missed the last three games due to a back problem and will be closely monitored, while midfielder Doyle has been sidelined for four games with an on-going groin injury.
Loanees Jon Stead and Adam Drury are expected to continue, the latter overcoming a knee injury in time for last weekend's home defeat to Oldham, but forward Andy Gray is recovering from the effects of shingles.
City have won only one of their last six matches and are six points above the relegation zone.
