In his presser, Misha was saying that it is hard to give his back the rest it needs to fully recover because of the schedule. I hope that he is able to rest it enough to do some real damage during the hard court swing. I would love to see him do one better at the USO this year and make it to the final.
He'd better take all time he needs to recover completely and start again brand new.
Back injuries can be very bad and very painful...
