The 26-year old Jamaican international joined Wanderers after a trial spell from Jamaican club Village United and was on the bench for the club's ill-fated FA Cup tie with Tranmere Rovers in January, however he has yet to make a first team appearance and is behind Jussi Jaaskelainen and Kevin Poole in the pecking order.
It was thought that the former Galaxy player was on loan to Bolton until the end of the season with a view to a permanent £300,000 transfer but this appears now not to be the case. Ricketts will ease the Eagles goalkeeping problems who have been decimated due to the long term injury of ex-Wanderer Matt Clarke.
