Gasol scored 10 points in 16 minutes prior to the injury.
The big man's left hamstring caused him to miss time earlier this season. ESPN's Adrian Wojnarowski reported on Dec. 19 that Gasol was expected to be out with a left hamstring strain suffered during Toronto's 112-99 win over the Detroit Pistons "for the foreseeable future," depending on his rehabilitation program.
The Raptors officially listed Gasol as "out indefinitely." He returned on Jan. 15.
The 34-year-old three-time All-Star averaged 7.7 points, 6.6 rebounds and 3.6 assists in 28.1 minutes per game across 34 starts heading into Tuesday.
The 2012-13 Defensive Player of the Year appeared in 26 regular-season games (19 starts) down the stretch for the Raptors, averaging 9.1 points and 6.6 rebounds in 24.9 minutes, but was most pivotal during Toronto's run to its first NBA title. Gasol averaged 9.4 points, 6.4 rebounds, 3.0 assists and 1.1 blocks in 30.6 minutes across 24 postseason games.
The Raptors depended on Serge Ibaka and Chris Boucher to split center duties while Gasol missed time in December, and they can do so again this time around.
