Olszewski expected to miss "weeks" after sustaining a groin injury during warmups before Sunday's 28-6 loss to the Vikings, Ralph Vacchiano of Fox Sports reports.

Olszewski has been dealing with a groin issue since mid-August, and after aggravating it Sunday, it appears he'll miss some time. It's currently unclear how many weeks Olszewski is expected to miss, but until the Bemidji State product recovers, expect Tyrone Tracy and Darius Slayton (concussion) to assume the Giants' kick- and punt-return duties, respectively.
