Boston Celtics point guard Kemba Walker has had nearly four months to rest and recuperate ahead of the NBA restart. Unfortunately, he still appears to be limited by the knee injury that has hampered him throughout the year.

Despite suggesting he was feeling healthy, Walker was held out of practice this past Monday due to discomfort in his knee.

However, after the All-Star guard went through a workout on Sunday, Celtics head coach Brad Stevens does not seem to be concerned and played down his injury woes.

Stevens said the team will be cautious with Kemba once he is ready to participate, suggesting that the veteran guard still has time to get back up to speed.

“With regard to Kemba getting back into it, I think ‘worrying' is a strong word,” the Celtics coach emphasized, via Chris Forsberg of NBC Sports Boston. “I think there's a lot more to worry about in the world right now so, when he gets back, we'll get him as acclimated as we can. I don't think it'll be as fluid in our first scrimmage, or whatever the case may be, as maybe three weeks from now. But there's time to do that. He practiced the first 50 minutes of today's practice, so he's done a lot more over the last few days.”

Kemba Walker has supplied the Celtics with vital scoring and playmaking when healthy.

The former UConn star was averaging 21.2 points, 4.1 rebounds and 4.9 assists while shooting 37.7 percent from beyond the arc on 8.8 attempts per game. Walker has also been a veteran leader for a team that owes a good deal of success to breakout campaigns from youngsters like Jayson Tatum and Jaylen Brown.

Perhaps the sore left knee will continue to give Walker trouble once play begins for the Celtics. But for now, Stevens is remaining optimistic.
