The NBA may move a step closer to adding teams in Seattle and Las Vegas next week when expansion will be again discussed by the league’s board of governors, two people with knowledge of the matter tell The Associated Press. It is expected that a vote on whether to go forward with those two cities as the sole targets for expansion at this time takes place next week as well, the people said. The people spoke on condition of anonymity because those were not released publicly. It would take a three-fourths majority of governors to go forward.
