Caroline Wozniacki faces a battle to be fit for the Australian Open after being reduced to tears during a dramatic defeat by Agnieszka Radwanska at the Sydney Tennis International.
Wozniacki lost 3-6 7-5 6-2 in a late-night quarter-final thriller.
The Dane's left wrist was strapped when trailing 1-2 in the deciding set, just five days before the start of the year's first grand slam.
Top seed Wozniacki served for the match at 5-4 in the second set before Poland's Radwanska hit a purple patch to run away with victory.
