Mabry reverted to the Seahawks' practice squad Monday, per the NFL's official transaction log.
Mabry received an opportunity with the active roster for Sunday's game against the Jets, after Will Dissly (knee) was placed on IR. The 26-year-old made the most of his opportunity, catching his only target for a seven-yard touchdown. Both the catch and touchdown were the first of his career. He'll likely have an opportunity to suit up Sunday against the Rams as well.
