Datsyuk injured his shoulder late in the third period of the Red Wings' preseason game against the Pittsburgh Penguins on Monday. Head coach Mike Babcock said the team was initially worried it was a more significant injury.
On Tuesday, Datsyuk had said he hoped to miss just one week and that he would have an MRI on Tuesday or Wednesday.
Datsyuk is coming off a season in which he was limited to just 45 games due to injures, the lowest total of his career. He scored 17 goals and had 37 total points in 2013-14.
The Red Wings are 1-1 in the preseason and play Thursday against the Chicago Blackhawks. Their regular season starts Oct. 9.
