The type of break he has is more of a pain in the a** than anything else. There's no surgery, not a ton of buildup of scar tissue(no huge range of motion issues), he's not out for 6 months and nothing is keeping him off of a treadmill, so conditioning won't be an issue. It just hurts like heck at first, then the swelling goes down, the pain chills out, it itches like crazy and when the cast does come off, one wrist will look smaller than the other. Enter Fletch. This is what he's paid for.
Hopefully, the x-ray in 3 to 4 weeks will show the bone will have healed and there's there is no additional pain. That part is just a roll of the dice. Everyone's healing timeline is different.
What could bother him is if he's required to wear protection on the wrist for awhile to keep it from getting banged around. They'll find something as comfortable as possible.
Just have to wait it out and do as much as possible in the interim.
On a much different note, this is why it's absolutely critical to make sure that you've developed a bench at EVERY position. We had guys on this board who thought it was totally appropriate to have Boswell and Wagler both pencilled in for 37/38 minutes each night. This situation was bound to happen whether it be because of foul trouble or injury, illness, family emergency, etc (regardless if it was one game or six). So, here we are having to replace 37/38 minutes with answers that are unknowns. If Kylan would have picked up three fouls in a half....same issue.
Hopefully, we come out stronger on the other side, where we don't have to run both guys into the ground because we'll have developed a quality minutes eater.
