ISNER: KNEE
NISHIKORI: KNEE
TSONGA: HAMSTRING
Guys to keep an eye on over the next week heading into Melbourne. The Nishikori and Tsonga injuries look particularly troubling. Isner scheduled for Sydney as the top seed, but seems iffy. Definitely look the draws for these guys in the AO and read up on their status leading up to the AO. Could save you some coin or help you make some going against them.
