It's unclear when Greenway injured his hand and what his exact prognosis is.
Greenway was limited in training camp due to a sore right wrist, the same wrist he sprained and later broke in two places last season. He was still able to play in all 16 games in 2013.
The 31-year-old has 10 tackles through the Vikings' first two games this season. Minnesota is 1-1.
