Kyrie Irving will re-join the Brooklyn Nets after the NBA championship-chasing franchise announced the part-time return of the All-Star for road games outside of New York and Toronto.

Irving is yet to play for the Eastern Conference-leading Nets this season due to his refusal to be vaccinated against coronavirus, which has prevented him from practising or playing with the team – New York has a mandate in place that states players must have had a COVID-19 jab.

At the start of the season, the Nets announced they would not accept Irving playing on a part-time basis and thus overlook him for selection until he is vaccinated.

But due to injuries and a COVID-19 outbreak, which has sidelined superstar and former MVP James Harden, Brooklyn have opted to bring back Irving.

"After discussions with our coaches, players and staff, the organisation has decided to have Kyrie Irving re-join the team for games and practices in which he is eligible to participate," Nets general manager Sean Marks said in a statement on Friday, with Brooklyn's next road contest against the Portland Trail Blazers on December 23.

"We arrived at this decision with the full support of our players and after careful consideration of our current circumstances, including players missing games due to injuries and health and safety protocols.

"We believe that the addition of Kyrie will not only make us a better team but allow us to more optimally balance the physical demand on the entire roster.

"We look forward to Kyrie's return to the line-up, as well as getting our entire roster back together on the court."

In 2020-21, Irving averaged 26.9 points, 4.8 rebounds and 6.0 assists per game as the Nets lost in the Eastern Conference semi-finals to eventual champions the Milwaukee Bucks.

Irving enjoyed a career-high 50.6 field-goal percentage and joint-career best 92.2 free-throw percentage last season.

With Harden missing the last three games while in health and safety protocols, Kevin Durant is averaging 39.7 points, 10.3 rebounds and 9.3 assists. The Nets are 3-0 in those games.
