Steve Clifford was announced Wednesday as the new coach of the Orlando Magic, a team that has missed the playoffs in each of the last six years. Clifford — who spent the last five seasons as coach of the Charlotte Hornets — was an assistant coach on Stan Van Gundy’s Magic staff for five years, including during the team’s playoff run in 2012.

Clifford is replacing Frank Vogel, who was let go after two seasons. Clifford, who missed 21 games this past season while dealing with severe headaches brought on by sleep deprivation, was fired by Charlotte at the end of this season after going 196-214.

Hiring Clifford is easily the biggest move made so far by Magic president Jeff Weltman. He took over the club a year ago after the team fired Rob Hennigan and ended his five-year run that never got on solid footing.

Clifford was ousted in Charlotte after a front-office shakeup. Owner Michael Jordan fired general manager Rich Cho and eventually hired Mitch Kupchak to replace him in April. Kupchak fired Clifford not long afterward.

The Hornets went to the playoffs twice in Clifford’s five seasons, never winning a series.

Hayward has surgery

The Boston Celtics say forward Gordon Hayward had surgery to remove a plate and screws in his broken left leg and will be ready to start next season.

Hayward missed almost the entire season after breaking his leg in the first quarter of the season opener. The Celtics went on to reach Game 7 of the Eastern Conference finals before losing to the Cavaliers.

The team says his leg and ankle are sound, but the plate and screws that were implanted to help the injury heal were irritating his tendons. He is scheduled to resume basketball activities in six to eight weeks and be ready for training camp.

Also Wednesday: the Celtics said center Aron Baynes had successful surgery to repair a nasal fracture he sustained during Game 6 of the Cleveland series. He is expected to be back on the court in two to four weeks.

Sixers investigate

The Sixers announced Wednesday that they have begun an independent investigation into Bryan Colangelo’s alleged secret use of Twitter. The Ringer, a sports and entertainment website, reported Tuesday night that the team’s president of basketball operations has five anonymous Twitter accounts, including four that have criticized Sixers players and coach Brett Brown and disclosed sensitive team information.

In a written statement released Wednesday morning, the Sixers said: “The allegations are serious and we have commenced an independent investigation into the matter. We will report the results of that investigation as soon as it is concluded.”

Colangelo acknowledged having one of the Twitter handles reported in the Ringer post, @phila1234567. He never tweeted from that account. However, The Ringer alleges that he also might operate four other accounts.
