World no 12 Sloane Stephens has suffered a setback ahead of the Australian Open after sustaining a wrist injury during the mixed teams Hopman Cup.
Stephens was forced to retire from her singles clash with the Czech Republic's Petra Kvitova in Perth.
The American lost the first set 6-3 before she retired, citing a problem with her left wrist.
Stephens now faces a race against time to be fit with the first Grand Slam of the year just two weeks away.
"It's something I've had in the past," said the 20-year-old.
"It was just too uncomfortable, it hurt too much to play so I couldn't finish.
"I'm going to have a few scans and see how it is.
"Hopefully it'll be okay for next week and then the Australian Open."
Stephens reached the semi-finals at last year's Australian Open, beating countrywoman Serena Williams in the quarter-finals before bowing out to Victoria Azarenka.
With the United States out of contention for the final, towering American John Isner also withdrew from their final tie. The world number 14 said he hurt his ankle earlier in the week.
Isner missed last year's Australian Open with a knee injury suffered at the Hopman Cup, and is due to play in Auckland next week.
