This may sound weird, but this is probably the best thing for Martin.
IMO, while he fights for a living, he's taken too many shots and his lights just go out so easily and he's one of this generation of fighters who I fear will suffer the after effects such as pugilistic dementia due to all the shots he's taken.
Not to say that Grove would've KO'd Martin, but Grove was in my opinion to high of a level fighter for Martin to be fighting. I genuinely fear for his wellbeing when I see him fighting.
This is a far more even-keeled matchup and probably best for everyone's health.
