Nowitzki was the three-point champion during All-Star Weekend in 2006, defeating Ray Allen and Gilbert Arenas in the final round.
Nowitzki has appeared in 16 games this year and is shooting just 26.1 percent from beyond the arc. He had ankle surgery last April, which not only kept him out for Dallas' first 26 games but is also clearly impacting his performance.
Nowitzki was a 40.9 percent three-point shooter in 2017-18 before his ankle injury forced him out of action.
His invitation is almost certainly a way for the league to honor the 40-year-old before he retires. Nowitzki is 11th all-time in made threes (1,930) and will be remembered as the best shooting big man in NBA history.
Given both his age and desire to avoid a yearlong farewell tour, the 2018-19 season could be Nowitzki's last in the NBA. Should that be the case, All-Star Weekend would provide fans with one more chance to enjoy Nowitzki on a big stage.
Since Nowitzki can still receive consideration for the Three-Point Contest into his 21st season, maybe the door isn't completely closed on LeBron James finally getting into the Slam Dunk Contest.
