Teams are adding veterans as they prepare for the postseason.
The San Antonio Spurs signed one-time NBA star Tracy McGrady for the rest of the season, according to Yahoo! Sports, and the New York Knicks announced they added veteran swingman Quentin Richardson.
Because they did not play for other NBA teams this season, both are eligible for the playoffs.
McGrady, 33, last played in the NBA during the 2011-2012 season, when he played 52 games for the Atlanta Hawks and averaged 5.3 points.
He worked out for the Spurs last summer, but wasn't offered a contract and became a free agent. He then signed to play for Qingdao in the Chinese Basketball Association and averaged 25 points for Qingdao this season.
Richardson, 33, has not played in the NBA since last season, when he averaged 4.5 points for the Orlando Magic. He was waived by the Magic last October.
---Los Angeles Lakers guard Steve Nash will not play in the team's final regular-season game against the Houston Rockets on Wednesday, but the Lakers hope he can play in the postseason if the Lakers get into the playoffs.
Nash has not played since March 30 because of a hamstring problem.
The Lakers can guarantee themselves a spot in the playoffs if they beat the Rockets. If the Lakers lose Wednesday and the Utah Jazz beat the Grizzlies, the Lakers will miss the playoffs.
--Cleveland Cavaliers All-Star guard Kyrie Irving apologized for skipping a postgame ceremony for fans following Cleveland's final home game on Monday against Miami.
"I want to personally apologize to all the Cavs fans for my actions yesterday," Irving wrote on Twitter. "It was truly unfair to you guys. I'm very appreciative for all of you guys. Your love and passion for the organization and city is what pushes me to be great."
