hi there, i am also a rugby player and injured my wrist in march 2010. i initially attended for an xray at that time and 2 weeks later to be told no signs of fracture (i played the 2 weeks inbetween). i continued to play with the wrist heavily strapped until the end of the season and then hoped it would settle with rest until pre-season. unfort when i returned to contact sessions in august it was as bad as ever and referred myself to ortho who re-xrayed only to find non-union of fractured scaphoid!!
obviously during the time continuing to work and play it did not heal. i had a cannulated screw inserted at the end of august 2010 and was not allowed to play / train for 6 months so not looking after this area now can lead to even longer on the sidelines and permenant problems!
i understand your eagerness to play and certainly there is certain tapings that can reduce the range of the wrist to reduce pain but you need to consider it carefully and balance up if this is worth it as if you play even with it taped and injure it further how long may you be out for?????
i also looked into wrist supports and although i have now returned to play i am still apprehensive about landing on my wrist and dont know if that will ever change.
i hope this is some help for you from someone who has been through similar concerns to yourself
cheers
