Yep, scaphoids...slowest healing bone in your body. I did both of mine in a Kawasaki/Security van interface. Took 12 weeks in plaster for me and my wrists still give me jip on cold days (luckily, riding the bike doesn't affect them) but if you don't let them heal properly you're also setting yourself up for arthritis when you get older.
Get well soon brave boy I have the greatest respect for you it's no fun racing with an injury so get it mended properly, we will keep your place for you as we need the close racing all the best mate.
