The Dallas Mavericks (7-20) will host division-rival San Antonio Spurs (19-8) at the American Airlines Center for the final time in the regular season Tuesday night. Head coach Rick Carlisle’s team has played better in recent weeks, and their past three losses have all come on the road against teams that should make the playoffs. The Spurs, on the other hand, have won their past four games in a row, and currently sit comfortably in third place, trailing only the Houston Rockets and Golden State Warriors in the Western Conference Standings. Greg Popovich rested many of his starters on the second night of a back-to-back Saturday, and his squad still managed to pull out a 104-101 road win over the Phoenix Suns. Star forward Kawhi Leonard is targeting his regular-season debut against Dallas Tuesday. Leonard has been sidelined this season with a quad injury.
