The Nigerian striker will stay on loan at Bristol City until the end of the season.
Bristol City boss Lee Johnson is delighted with the boost that his relegation threatened team will get with the arrival of Odemwingie.
Johnson said: “I’m delighted we’ve been able to bring someone of Peter’s quality in; he’ll provide us with experience and hopefully goals in one form or another.
“I’m looking forward to working with him and he’ll be available for us at Fulham tomorrow.”
