Dwight Howard, who hasn't played since Jan. 30 because of edema in his right knee, expects to be back in two weeks, he told ESPN's Lisa Salters on Wednesday. Howard worked out on the floor after the Houston Rockets' shootaround Wednesday morning in Portland, doing one-on-one work for the first time since a bone marrow aspirate injection in early February. It was his first one-on-one work against a defender, although he's entering his second week of on-court activities. He told Salters that his knee feels good, he hasn't had any problems or setbacks and his conditioning is good.
