DALLAS -- The NBA issued a two-game suspension to Dallas Mavericks public-address announcer Sean Heath due to tweets criticizing officiating, multiple sources briefed on the situation told ESPNDallas.com.

The suspension will begin Saturday night, when the Mavs face the Phoenix Suns in their final home game of the regular season. Heath will complete the suspension either in the first home game of the playoffs or next season's home opener, depending on whether the Mavs advance.

Heath, who declined to comment, wrote a series of tweets regarding the officiating after the Mavs' 122-120 overtime loss to the Golden State Warriors on April 1.

The league office acknowledged in a statement the next day that Warriors center Jermaine O'Neal should have been called for goaltending when he blocked a potential go-ahead shot by Mavs guard Monta Ellis with 16 seconds remaining in overtime.

Three of the tweets from Heath's account with 253 followers were directed to the NBA's account, the most inflammatory of which said that games such as the Mavs' loss to the Warriors are why the league has a "reputation that the games are rigged."

@nba Danny Crawford just blew a goaltending call and cost the Mavs a game. We will all be awaiting your apology. #pathetic - Sean Heath (@theseanheath) April 2, 2014

@EyeOnBasketball That headline should read: Danny Crawford buries Mavericks. Again. - Sean Heath (@theseanheath) April 2, 2014

@nba If you have the technology to get calls right, we'd all LOVE to see it implemented as soon as possible. These. Games. Matter. #thefans - Sean Heath (@theseanheath) April 2, 2014

@nba : The ONLY professional league in the US with the reputation that the games are rigged. Know why? Because of games like tonight. #shame - Sean Heath (@theseanheath) April 2, 2014

Sources said that the league issued the suspension Thursday but granted a request from the Mavs to postpone it until the next game to give the team time to find a suitable replacement for Heath, who is known for his high volume and passion.
