The Buffalo Bills received unwelcome news on Thursday as veteran safety Sam Franklin Jr. appeared on the injury report as a limited participant due to a shoulder issue.

The designation marks a sudden development for a player who had been practicing without restriction earlier in the week, raising questions about his availability for Sunday’s road game against the New York Jets at MetLife Stadium.

Franklin has carved out a specialized role in Buffalo this season.

While he has logged just a single defensive snap, he has been a regular presence on special teams, taking part in roughly three-quarters of those plays.

His absence, if it extends to game day, would thin the unit at a moment when the Bills are still sorting through their secondary depth chart.

The team has not yet assigned a formal game designation, which typically comes after Friday’s practice, and officials have offered no further details on how or when the shoulder problem surfaced.

The timing coincides with significant recent movement at the position. Just before the NFL trade deadline, Buffalo acquired Amani Hooker from the Tennessee Titans, sending a second-round pick in exchange for Hooker and a fifth-round selection.

Hooker, who has been among the league’s more productive safeties, indicated midweek that he expects to play against the Jets and is already familiar enough with common coverage concepts to contribute immediately.

The Bills had previously released C.J. Gardner-Johnson following a suspension, leaving Damar Hamlin and practice-squad option Geno Stone as the primary alternatives until Hooker’s arrival.

Franklin’s status is one of several injury concerns heading into the matchup.

Starting right tackle Spencer Brown was held out of Thursday’s session after being limited the day before, while cornerback Christian Benford, tight end Dalton Kincaid, and offensive linemen Alec Anderson, Dion Dawkins, and Connor McGovern were among those listed as limited participants.

The offensive line in particular has drawn attention as the Bills manage a collection of nagging issues.

Even with the health questions, Buffalo enters the contest as a clear favorite. A victory would push the Bills to 7-1 and further separate them from the New England Patriots in the AFC East standings.

The Jets, by contrast, have struggled through the early portion of the season, giving Buffalo an opportunity to maintain its position among the conference’s top teams.

Whether Franklin can clear the shoulder issue in time remains uncertain, but his potential absence underscores the value of the depth the Bills have worked to assemble on both special teams and defense in recent days.
