Dulin won't return after suffering a concussion during the second quarter of Monday's game against the Chargers, Zak Keefer of The Athletic reports.
The injury in question occurred after the receiver attempted to catch a pass in the flat before Chargers safety Derwin James blew up the play with a helmet-to-helmet hit that drew a targeting penalty and an ejection for the defender. Dulin finishes Monday's game without a reception across eight snaps.
