Leon Smith talked about this the other day and said he was confident Andy would play as it's prolonged play on clay which aggravates the back and he didn't think one w/e would be a problem. But that might be more hope than confidence and I think Andy would be wise not to do it. It's not axiomatic he'd even win his matches on clay.
I'm not convinced Andy should chance it. I still can't persuade myself that DC matters as much as his own career. I don't mean to him, but in the bigger picture.
