World number two Simona Halep said Tuesday that she will miss Romania's Fed Cup tie with Canada this weekend after an injury picked up at a gruelling Australian Open failed to heal. "After spending the last week resting and rehabbing my injury from the Australian Open, unfortunately it has not recovered quickly enough," the 26-year-old said on Facebook. "I'm sad as playing for Romania is very important to me but I look forward to seeing everyone in Cluj as I will travel to support my teammates in this very important tie. Good luck Romania!"
