The Toronto Raptors will be hoping Kyle Lowry is fit to feature against the Boston Celtics after easing through to the second round of the NBA playoffs.
Toronto completed the first series sweep in franchise history on Sunday, though a fourth straight victory over the Brooklyn Nets may have come at a heavy price.
Lowry played just nine minutes of the 150-122 triumph that sealed the Raptors' progress, with head coach Nick Nurse revealing in his post-game media call that the point guard suffered an injury to the arch of his left foot.
The six-time NBA All-Star will wait for results from an MRI scan to discover the damage, leaving the defending champions unsure if they will have one of their key players available to face the Celtics.
However, Nurse - who described Lowry as a "big engine" for the team - hopes others can step up to fill the void, whether individually or collectively as a group, if the 34-year-old is sidelined.
"I won't be very comfortable without Kyle out there - he's a big engine for us," Nurse told the media.
"But I would say that we play a system or a style where lots of guys are involved.
"We're going to miss all of those great things that Kyle does if he's not playing, but someone else will take shots, play defense, play tough, do all the things he does and make up for it. Or, we do it by committee, which is probably the better way."
He added: "You've got to go out there with who is healthy and available, and you've got to think there is a good chance you can figure out a way to win. That's what we will do, either way."
Despite being without Lowry, Toronto coasted past the Nets. Norm Powell had 29 points and Serge Ibaka contributed 27 as the bench came up big in Game 4, contributing 100 points to the cause.
Still, they will hope to have one of their key players on the floor when they open the series against the Celtics, who impressed Nurse with the way they swept past the Philadelphia 76ers, on Thursday.
"I think they're really good," he replied when asked about Toronto's next opponents.
"They are super-talented, really deep and very well coached. I think they're playing great at the moment.
"They put away a very talented Philadelphia team with ease, with ease. There was never a doubt in that series where it was going, bar maybe a little bit in one game.
"I'm hoping it's a great series. We're going to need to play good to beat him."
