Toronto Raptors guard Carlos Delfino was injured over the weekend and might miss part of the FIBA Americas Championship, according to a report in an Argentine newspaper.

Delfino injured a knee in the Tuto Marchand Cup and could sit out Argentina's game against Uruguay in Las Vegas on Thursday.

"It is the same knee I underwent surgery on two years ago and that's what makes me worry most, as I cannot stretch the leg too much," Delfino told La Nacion newspaper on Sunday.

"I know it's not serious, but I worry because I cannot get out of my mind memories about how much I have suffered with this knee."

Delfino underwent an MRI scan on the injury. National team doctor Diego Grippo said he felt optimistic after seeing the results.

"Delfino has a kneecap tendonitis provoked by a blow that limits the movements of the knee, but physiotherapy will help it disappear in a few days," Grippo said. 

Raptors GM Brian Colangelo confirmed that Delfino's injury is not critical.

"We are aware of his situation and are monitoring his progress," he said. "At this point it is not thought to be serious."

Delfino could be the third Raptor to pull out of international competition with an injury this summer.

Chris Bosh left the U.S. team earlier this week due to plantar fasciitis in his foot, while Spanish forward Jorge Garbajosa still hasn't been cleared to play following leg injuries he sustained in the regular season.

Toronto acquired Delfino from the Detroit Pistons for two second-round draft picks on June 15.

The FIBA tournament, which begins Wednesday and runs until Sept. 2, will serve as the qualifier for the Beijing Olympics. The top two teams will earn automatic berths, while the next three top-ranked teams will be invited to the FIBA World Olympic Qualifier, which will be held next July.
