Wallace, who retired after 15 seasons in 2010, has been working out and probing some close league friends about possible destinations to sign for the rest of the season, sources said. At 6-foot-11, Wallace, 37, had been one of the most versatile and talented power forwards of his era. One league source who has talked with Wallace recently describes him as "serious" about a return to the NBA this season. Nevertheless, no teams contacted by Yahoo! Sports reported that they had any contact with Wallace, or his representative.
