Just when it looked like Ian Mahinmi was turning a corner, the Wizards center has been sidelined with a right knee strain and his status is up in the air for Tuesday's game at the Brooklyn Nets. Mahinmi didn't participate in the Wizards' practice on Monday, according to NBC Sports Washington's Chris Miller, and will be evaluated pregame. Mahinmi has yet to miss a game this season, one of six players to appear in all 26 of the Wizards' games. Last year, he played in only 31 of their 82 games due to injuries. Those injuries included a host of knee problems. Mahinmi had surgery to repair a partially torn meniscus in his left knee last October. After that he developed tendinitis in his right knee and underwent platelet-rich plasma treatment in both knees in December. Mahinmi also had a left calf strain in April that caused him to miss games in the playoffs. He then had a minor procedure involving his meniscus in his left knee early in the summer.
