Birmingham have bolstered their Championship promotion push with the twin captures of Peter Ramage and Caleb Folan.
Versatile 28-year-old defender Ramage has joined on loan from QPR until the end of the season, having spent the first half of the campaign with Crystal Palace, making 23 appearances between August and January.
Former Hull striker Folan has been on trial at City since his release by MLS side Colorado Rapids at the start of February, impressing manager Chris Hughton.
The 29-year-old moved to the US from Hull in March 2011 but lasted less than a year across the Atlantic before mutually parting ways with the Rapids on February 3, having scored six goals in 26 appearances.
Hughton has been busy in the transfer market recently, with forward Erik Huseklepp and winger Andros Townsend arriving on loan deals from Portsmouth and Tottenham respectively last week.
