The former Everton star has missed much of the season with a hamstring injury, but featured in Wednesday evening's penalty shootout win over Rochdale.
"I've missed a lot of football and not had a lot of gametime," Rodwell told the club's website. "I've not trained too much which is why I've played the full 90 minutes tonight. I'm really pleased.
"I'm fit and we'll just see, I've not trained too much but I'm fit and available for selection."
Rodwell has scored two goals in 12 appearances for City since joining to club in 2012.
