Having once applied for and been granted my own registered trademark for an old business I used to have, I can categorically say that RTMs (that little ®) are a massive legal minefield and there are specialist lawyers in that field alone.
Now, if the RTM is only applicable to a particular category then there's nothing legally to stop you using an exact copy of whatever RTM you like in a totally different product class or category. Now, finding out what categories the relevant RTMs apply to is a simple enough process of you care to delve through the IPO archives (available online) so that you would know for sure whether the RTM you want to copy has been granted to cover its use on the jersey (e.g. If the mark applies only to bicycles or bicycle components in any relevant class or category then using that mark on any item of clothing is totally legit). But, as said, it's a legal minefield even for genuine rip-offs in the same classes or categories and lawyers, if instructed, would have a hard enough job battling such a case, even if the respective RTM owner were bothered to pursue litigation for an infringement or use of their mark without express permission.
Bottom line: just do it. (Pun intended - as Just Do It is an RTM of NIKE, but it probably doesn't cover its use in the context in which I've just typed it )
Now let the floodgates for orders of replica jerseys open...
