Nets guard Joe Johnson felt pain in his left heel in two games before All-Star weekend. He felt it again following the break, but still sank the Bucks on Tuesday with a game-tying 3-pointer and then a game-winning overtime jumper. He flew with the team to Milwaukee and went to bed.

The problem was when he tried to get up.

“I got in the bed in Milwaukee and woke up the next day,” recalled Johnson, who sat out Friday’s game and is listed as questionable for tonight’s against the Grizzlies at Barclays Center. “I had to literally crawl out of bed because it was hurting so bad.”

On whether he will face Memphis, he said simply, “I’m not sure.”

After the Nets’ light practice yesterday, Johnson explained how he had figured he just needed to loosen up his heel, which he described as badly bruised. He played through pain Wednesday. He shouldn’t have.

“It never loosened up but ... I played through it. It was tough,” said Johnson, who has undergone all the usual treatments — ice, massage, laser stimulation — and some exotic stuff like hot yoga to help the heel.
