Dirk Nowitzki said it was "a little sinus infection" that caused his fever, but he said he will be ready to go Thursday.
North Texans who battle sinus infections can feel for the Big Nowitzki.
Nowitzki was sniffling constantly and coughing at times in his postgame media session.
He said Jason Terry was "phenomenal" in the game.
Nowitzki said he went a little early on his virtual game-deciding drive that gave the Mavericks a three-point lead because he saw a little opening as the defender, as always wanted to force Nowitzki to his right.
