The fracture is "stable" and "non-displaced," according to the program, and Dawson could return in time for the Spartans' Big Ten opener on Dec. 30 against Maryland.
With 15:30 remaining in the second half, the senior fell awkwardly on his wrist after a dunk attempt. Dawson went to the locker room and later returned to the bench with his left hand wrapped in ice but did not check back into the game.
Dawson broke the same hand last season, an injury which forced him to miss nine games before he returned toward the end of February.
The Spartans went on to defeat the Eagles 66-46 on Wednesday night. Dawson had four points and seven rebounds in 18 minutes.
Dawson is Michigan State's leading rebounder (8.5) and is tied for third on the team in scoring (11.6).
The Spartans are 8-3 this season after defeating the Eagles on Wednesday.
