Err on the side of caution, B2B. All sorts of stuff can come and go in ten weeks, I imagine we'll all have a few wobbles on the way to the start line. If you're fit enough for a 50 you can manage a 100, training will just dictate how comfortable it might be, but if you aggravate an injury it's a different matter. Maybe you could try some walking training, I know it's tough as we like to think of ourselves as runners, but I usually end up regretting not practicing the walk (or 'power hike' as those with an ego say) as come race day I do a lot of it.
Good luck with the recovery anyway.
