Toronto FC may be without goalkeeper Julio Cesar for the remainder of the 2014 MLS season.
The 34-year old is set to represent Brazil at the 2014 World Cup but could be called back by parent club QPR later in the summer as they prepare for the possibility of playing Premier League football next term.
QPR meet Derby County in the promotion play-off final at Wembley on the weekend and may call Cesar back from his loan if they are successful.
"I don't know," he said. "It depends on the World Cup.
"Queens Park Rangers wants me in August. I don't know what will happen.
"I'm contracted still in England for a few more years. I'm contracted to return there in August after the World Cup.
"I can't really give you a clear answer as to what my fate is after the World Cup. I've always been a professional person.
"Even if I win the World Cup, I'm going to keep to my word, return to my [parent] club and help them win championships."
Cesar joined TFC from the R's in February and appeared seven times for the Canadians before being called into Luiz Felipe Scolari's Selecao for the home tournament which kicks off in Sao Paulo against Croatia on June 12.
