DENVER - Tests on Andrea Bargnani's injured calf muscle revealed no significant damage, but the Toronto Raptors have no timeline for his return.

The Raptors forward reinjured his strained calf in the first overtime of Wednesday's double-overtime victory over Utah and underwent testing Thursday in Denver.

The team says the Italian will be sidelined indefinitely.

Bargnani originally injured his calf Jan. 11 against Sacramento and missed six games from January 13-22.

Bargnani is Toronto's second-leading scorer, averaging 23.5 points and 6.4 rebounds in 13 games. He has scored 30 or more points in four games, including 36 in his return to the lineup Tuesday in Phoenix.

The Raptors continue their road trip Friday night against the Nuggets.
