Phoenix Suns guard Devin Booker will step in to replace injured Los Angeles Laker, Anthony Davis, in the 2021 NBA All-Star Game.

Davis is suffering from Achilles tendinosis and a strained right calf, leading to commissioner Adam Silver to choose Booker as an alternate, one day after he was overlooked by league head coaches.

Booker joins Suns team-mate Chris Paul as a 2021 All-Star, earning his second selection after making his debut last season.

The duo have led Phoenix to the fourth-best record in the competition, 20-10, setting their team's best record through 30 games in the past 13 years.

The All-Star captains, Lakers superstar LeBron James and Brooklyn Nets ace Kevin Durant, will draft their rosters on March 4 for the game at State Farm Arena, Atlanta, on March 7.

Seventeen-time All-Star James had tweeted: "Devin Booker is the most disrespected player in our league!!! Simple as that," after Booker was snubbed from the All-Star reserves list.

Booker is averaging 24.7 points, 4.3 assists and 3.8 rebounds during the 2020-21 season and has dropped a career-high 50.1 per cent of his field-goal attempts.
