Kendrick Perkins expressed his concerns about Boston Celtics’ superstar, Kemba Walker, and his recovery from a knee injury.

The current ESPN analyst said what concerns him is that Walker is still dealing with the injury, even though he sustained it in February.

“Well, Greeny, you said, ‘If Kemba Walker is healthy… ” If ‘if’ was a fifth, we’d all be drunk. I have major concerns about Kemba Walker. Listen, he had a four-month layoff and he’s still not all the way healthy. They need him down the stretch. He was their closer when Jayson Tatum struggled.

He’s their guy. He’s their second All-Star. So, with that being said, when you look at the Toronto Raptors and the Boston Celtics, I think they cancel each other out at the guard and wing positions, but I’m gonna go with (Jay Williams’) point and talk about their bigs,” Perkins said, via Ricky Doyle of NESN.
