Lee, who netted on his debut in the win at Aldershot, told the Advertiser: “Hopefully I can bring a bit of energy to the team, get forward, make a few assists and get a few goals.
“I started the first five matches of the season at Peterborough and then didn't play a game and for the last four I've not been involved.
"Thankfully Rotherham have given me the opportunity to come here and get some games for a month. The plan is to play the seven games and then after 28 days we'll see what the situation is.
“I just want to play at as high a level as I can and if it means coming to Rotherham to do that with the possibility of getting promotion then that could be a possibility.”
