Since Bobby Lashley is officially in TNA?

Since Bobby Lashley is now with TNA and he is legitimately undefeated in 4 MMA matches, how is TNA gona go about having Lashley job? Cuz it wouldn't make since having an undefeated MMA fighter doing the job to random TNA wrestlers. Then again, if they don't make lashley do the job until he loses in real life (which could be a LONG time) they run the risk of having an undefeated streak that would be ridiculed and compared to goldberg and samoa joe
