Jason MacDonald has suffered another setback and will be pulling out of his UFC 124 bout with Rafael Natal due to a training injury, according to MMA Junkie. Replacing MacDonald will be Canadian MMA veteran, Jesse Bongfeldt (21-6, pictured above with Randy Couture), who owns a submission win over TJ Grant, and has been to a decision only once in his 27-fight career.
