Dwight Howard, once one of the most dominant players in the N.B.A., is poised to get yet another shot to resurrect his troubled career, this time in a return to the Los Angeles Lakers.
Howard, a 33-year-old center who spent a contentious season with the Lakers in 2012-13, has agreed to a buyout from the Memphis Grizzlies, and he is expected to sign a non-guaranteed deal with Los Angeles after the buyout is official and he clears waivers, according to a person with knowledge of the negotiations who was not authorized to speak publicly.
