It's all about the ankles: Joe Johnson out; Deron Williams reveals additional cortisone shots.

Joe Johnson has been the Nets iron man all year, not missing a game, leading the team in minutes as well as clutch shots. But against Houston, we will get a look at his collection of suits for the first time. He has a sore ankle. It bothered him Wednesday, the first time all year he failed to score in double digits.

Billy King spoke about Johnson's injury on ESPN Radio: "He has a sore heel, like the plantar fasciitis. It’s affected him. It started hurting the 2nd game in Milwaukee and yesterday it was still sore. It’s sore again today, it’s gotten better, but we’re going to keep him out tonight.

"It’s going to be day-to-day. It’s better ... they’ve got him on medication and I expect to be much better tomorrow."

The Nets play the Grizzlies Sunday.

Meanwhile, Deron Williams provided more details on the treatment regimen for HIS ankles (plural).

Williams revealed Friday he's gotten cortisone shots in both his ankles three times this season (before the season, in January and Thursday.) King, interviewed on ESPN Radio, was asked if he has to change expectations for D-Will moving forward due to injuries: "No, no, not at all"
