Midfielder Frecklington has missed the last 11 games with an ankle injury but has been passed fit to be included in Gary Johnson's squad.
However, playmaker George Boyd remains a doubt after he turned an ankle in training which forced him to miss out on the win over Walsall last Monday and the FA Cup defeat at Fulham at the weekend.
Midfielder Charlie Lee is also battling an ankle injury which has ruled him out of the last two matches.
New signings Kieran Agard and Jonathan Obika are both available to make their league debuts after coming on against the Cottagers.
Agard has arrived from Everton while fellow striker Obika is on loan from Tottenham.
