That heavy foot the Dallas Mavericks planted firmly on the gas when they beat Denver by 28 points on Friday night was sorely missing Sunday night when the Mavs hosted the Nuggets for the second time in three days at American Airlines Center.
Michael Porter Jr. nailed the game-winning three-pointer with 55.6 seconds remaining as the Nuggets regrouped and hung on to upset the Mavs, 98-97, before a sellout crowd of 20,244. The Mavs (9-7) had a chance to win the game in the end, but a long three-pointer by Luka Doncic hit the rim and fell harmlessly away as time expired.
