Mahut may have a tough decision to make if the match is rescheduled for tomorrow. He loves playing all the grass warm up events but at 34 he may have to consider pulling out. Instead they could just schedule the R1 match on Wednesday to help Mahut have time to recover and get here.
I don't think it was 100% confirmed that Andy would play R1 on Monday. It was only a BBC article that said he was.
Last year R1 was played over Monday and Tuesday, with Andy playing on the Tuesday. I kind of assumed after the long clay season this is what would happen again this year.
Queens has its own weather issues today, possibly the whole week, so they may still be playing qualies tomorrow.
Mahut is defending champion in S'hertogenbosch isn't he? He's had a lot of success there over the years, so I can see him wanting to try and defend it again.
