Broken Wrist and Off Season

Almost 2 weeks ago I was mountain biking on some trails, when I fell and broke my wrist. When I got it checked out by a doctor they thought I might have broken it in 2 pieces, so I have to wear a cast with a thumb piece for 3 weeks. I have kept riding, but the hardest thing to do is shift. It's also hard to put my hands on the bars in some ways, but at least it's the off season. Sadly, I don't have another race until mid February, about 3 months from now.
