Milos Raonic's return to tennis could be on hold.
The hard-serving 20-year-old from Thornhill, Ont., fell ill earlier this week after arriving in Israel for Canada's Davis Cup tie against the host country.
Raonic was hit with a bug, says Davis Cup captain Martin Laurendeau, and his status for Friday's second singles match against Amir Weintraub is uncertain.
"He's in the process of recovering and getting his strength back," Laurendeau said during a conference call Thursday.
"He wants to play. He trained this afternoon, he's really worked hard to be here and play for Canada. He deserves to play and he will if he can."
Raonic hasn't played since injuring his hip at Wimbledon in June. If he cannot play Friday, the team will go with Peter Polansky of Thornhill in the opener.
Raonic is also scheduled to play the first singles match on Sunday.
Raonic, 31st in this week's ATP rankings, is Canada's highest ranked singles player ever.
