ISO a Non-Life Threatening Injury

I've actually been writing today! I've managed almost 1,000 words so far - and considering I did less than twice that in the whole past week, I'm feeling pretty good.

My sister-in-law kidnapped my daughter for the day, my husband took off for the lake ... and I've felt inspired to do something. BUT... I have a small plot problem that I thought I'd throw out and see if any of you have ideas.

In Camilla, I need to have my hero injured and bedridden for a few weeks. Originally, I have him falling off the barn roof and breaking a leg and a hip -- effectively putting him in a spica cast for at least six weeks.

That's just too long. I need something that will keep him essentially bedridden for more like 2 - 3 weeks instead (though at some point he can use a wheelchair to get around if necessary). Any ideas? I would kind of like him to still fall off of the roof, though, if possible. Or something else that would make my heroine feel like it was her fault he was hurt.

Anyone?
