Former Olympic and world 100 metres champion Maurice Greene will miss this week's US championships in Indianapolis because of a leg injury, his manager said on Monday.
"It seems that as he got over one leg injury two weeks ago, he started pushing it at practice and injured the other leg," Emanuel Hudson said in an e-mail to Reuters.
The 32-year-old Greene has run sparingly over the past two years because of foot and leg injuries
Hudson said Greene, a three-times world champion and former world record holder who still holds the American record at 9.79 seconds, is not ending his career.
"He does intend on running this European season so he will continue to rehab and train," Hudson wrote.
