According to topmmanews.com:
Ed Ratcliff has unfortunately been forced to withdraw from his showdown this Sunday at WEC against the "Polish Hammer" Chris Horodecki. Top MMA News was unable to determine the reason behind Ratcliff’s withdrawal. Last night, word spread that the organization was looking for a 155er that was medically cleared and ready to step in against Canada’s 4th Ranked Canadian Lightweight.
Stepping in to replace Ratcliff this Sunday is unbeaten 24-year-old Danny Downes of Milwaukee, Wis.
The Duke Roufus-trained product is 6-0, with five wins coming by way of knockout. Known for his electric striking, Downes is also a cerebral fighter who owns degrees in International Affairs and German from Marquette University.
