The Charlotte Hornets completed the acquisition of Gordon Hayward in a sign-and-trade with the Boston Celtics, it was announced on Sunday.

Hayward – an unrestricted free agent – moves to the Hornets along with a 2023 and 2024 second-round NBA Draft pick in exchange for a protected 2022 second-round selection.

While terms of the contract were not disclosed, Hayward has reportedly signed a four-year, $120million deal in Charlotte.

Hayward was due to earn $34.2m with the Celtics in 2020-21, but the 2017 All-Star opted to leave Boston after three years.

"We are thrilled to welcome Gordon and his family to the Hornets organisation and Charlotte," said Hornets president of basketball operations and general manager Mitch Kupchak.

"Gordon is an NBA All-Star, a proven scorer and playmaker and a tough competitor that will fit well into the needs of our team.

"We believe that his basketball talent, NBA experience and veteran leadership will make a positive impact on our young, talented team as it continues to develop."

Hayward left the Utah Jazz for the Celtics on a four-year max contract via free agency in 2017, but he endured a difficult time in Boston.

The ninth pick in the 2010 NBA Draft, Hayward suffered a gruesome fractured tibia and dislocated ankle in his first game for the Celtics three years ago.

Hayward struggled to recapture his best form the following season, and the 30-year-old sustained a broken bone in his hand in November before suffering a sprained right ankle during Boston's sweep of the Philadelphia 76ers in the opening round of last season's playoffs in Orlando.

He did not return until midway through the Eastern Conference finals against the Miami Heat.

Hayward averaged 17.5 points, 6.7 rebounds and 4.1 assists per game for the Celtics last season, having averaged 11.5 points, 4.5 rebounds and 3.4 assists in 2018-19.

Since entering the league, Hayward is averaging 15.3 points, 4.4 rebounds and 3.5 assists per game.
