Head coach Jeff Blashill said Wednesday that Greenway tweaked a lower-body injury and is considered day-to-day, Scott Powers of The Athletic reports.
Greenway appeared in Monday's 4-3 overtime win over Minnesota. He may sit out the rest of the exhibition schedule, but it's unclear if he will be available for Tuesday's regular-season opener against the Golden Knights. If Greenway is ready, he'll likely handle a bottom-six role.
