Collison tried to play through the sickness on Friday but could only gut it out so long, according to Eddie Sefko of the Dallas Morning News.
"I tried to push through it, but I was just too weak," Collison told Sefko after the game.
Collison only played 10 minutes and was largely ineffective. He recorded two assists, one rebound and took one shot, scoring zero points. He walked back to the locker room towards the end of the third quarter.
Collison is averaging 6.8 points, 2.6 assists and 2.4 rebounds this season in 25 minutes of action per game. He lost his starting job to Derek Fisher after the Mavericks signed the veteran point guard on Nov. 30. Collison started Friday night, however, as Fisher is out with a knee injury.
