The Dallas Mavericks will sign Dirk Nowitzki to a two-year deal, locking him up until he is 40-years-old, per ESPN's Marc Stein.
Reports had been overwhelmingly pointing towards Dirk staying in Dallas, and so this signing doesn't come as any sort of surprise.
Dirk finished the season ranking 42nd with a 4.1 nERD, averaging 18.3 points and 6.5 rebounds per game with a .555 true shooting percentage.
