TORONTO (AFP) - Yet another injury scare for Chicago point guard Derrick Rose took much of the excitement out of the Bulls' 100-93 National Basketball Association victory on Thursday at Toronto.

Central division leader Chicago matched Atlantic division leader Toronto for the best record in the Eastern Conference, as both teams left the court with seven wins and two losses.

Rose, playing consecutive games for only the second time this season due to sprained ankles, scored 20 points. But he walked off with just under two minutes remaining in the fourth quarter after falling to the floor. He walked slowly to the bench after appearing to tweak his already sore left ankle.

The Bulls said Rose injured his hamstring and would undergo an MRI exam on Friday.

Rose, the 2011 NBA Most Valuable Player, injured his left knee in 2012 and missed the entire 2012-13 campaign, then injured his right knee early in the 2013-14 season and missed the rest of that run.

Against the Raptors, Spanish big man Pau Gasol scored 27 points and grabbed 11 rebounds, both game highs, to spark Chicago's victory.

The Bulls also had 21 points from Jimmy Butler and 14 from Mike Dunleavy.

The Bulls outscored the Raptors 35-14 in the third quarter and led by 18 points before Toronto made a late 14-1 run to produce some drama.

But in the end, the Bulls improved to 5-0 on the road for the first time since 1996 in Michael Jordan's heyday with the club.

The Raptors, who had been 5-0 at home this season, were led by Kyle Lowry's 20 points. DeMar DeRozan struggled with 3-of-17 shooting from the floor and managed only 10 points.
