Bianca Andreescu’s season debut has been delayed again after the Canadian tennis star withdrew from this week’s Credit One Bank Invitational, according to the tournament website.
The tournament is scheduled to begin Tuesday in Charleston, Va.
She was replaced in the draw by Caroline Dolehide of the United States.
Andreescu, currently ranked sixth in the world, won her first WTA title at Indian Wells last year and then beat Serena Williams in the finals at Toronto and again at the U.S. Open in Flushing Meadows to clinch her first Grand Slam crown.
The Mississauga, Ont., native hasn’t played a competitive match since October after suffering a left knee injury at the WTA Finals in Shenzhen, China. The injury lingered and forced Andreescu to sit out the Australian Open in January and an event in Dubai two months later before tennis was shut down in March due to the coronavirus pandemic.
Canadians Leylah Fernandez and Eugenie Bouchard are playing at this week’s tournament, which features 16 players divided into two teams with Americans Madison Keys and Bethanie Mattek-Sands serving as captains.
There will be 16 singles matches and eight doubles contests.
