During the Dallas Mavericks' loss to the New Orleans Pelicans on Monday night, Dirk Nowitzki scored a modest eight points, but in doing so, he passed Wilt Chamberlain for sixth on the NBA's all-time scoring list.

On Tuesday, Nowitzki's former teammate, Jason Kidd, took to Twitter to congratulate Nowitzki for the achievement:

Kidd spent four-and-a-half seasons with the Mavericks, winning a championship with Nowitzki in 2011 and making an All-Star team in 2010.

Nowitzki is in his 21st year in the NBA, and the general consensus is that he will be retiring at the end of this season. He has not made any formal announcement about his plans, but based on the way the 40-year-old has looked, it seems like the end is near.

In 39 games this this season, Nowitzki is averaging 6.1 points and 2.4 rebounds over 13.7 minutes per game while shooting 35.5 percent from the floor, 30.2 percent from three-point range and 74.4 percent from the free-throw line.

Nowitzki was originally selected by the Milwaukee Bucks with the ninth overall pick of the 1998 NBA Draft but was immediately traded to Dallas for the late Robert “Tractor” Traylor.

The big German then went on to become one of the best power forwards in NBA history, earning 13 All-Star selections and then being named a special addition to this year's All-Star Game by NBA commissioner Adam Silver.

Nowitzki also won an MVP award in 2007, and, most importantly, captured an NBA title and Finals MVP in 2011 after leading the Mavericks to an upset win over the Miami Heat.
