The Demetrius Flannigan-Fowles injury has created another challenge for the Buffalo Bills as training camp continues.
Buffalo officially placed the veteran linebacker on injured reserve after he suffered an undisclosed injury during practice, ending his bid to earn a role on the team’s 53-man roster.
While the Bills have not revealed the exact nature of the injury, the move immediately opened a roster spot and prompted Buffalo to sign linebacker Otis Reese IV. Here are the five biggest facts fans should know about this developing situation.
1. The Bills Placed Flannigan-Fowles on Injured Reserve
The biggest development is simple: Buffalo moved Demetrius Flannigan-Fowles to injured reserve following a training camp injury.
The team has not announced how serious the injury is or whether he could return later this season. For now, his 2026 training camp has come to an abrupt stop.
This move also clears a roster spot as the Bills continue evaluating players ahead of the preseason.
2. He Was Signed to Add Veteran Experience
Flannigan-Fowles joined Buffalo earlier this offseason on a one-year contract after spending last season with the New York Giants.
Before arriving in Buffalo, he played six seasons with the San Francisco 49ers, where he built a reputation as a dependable linebacker and one of the team’s top special teams contributors.
His NFL experience made him valuable depth behind Buffalo’s younger linebackers.
3. Buffalo Quickly Signed a Replacement
The Bills wasted little time replacing the veteran.
Following the injury, Buffalo signed linebacker Otis Reese IV, who had recently worked out for the organization.
Reese now receives an opportunity to compete for a backup linebacker role while also providing depth on special teams.
Fast roster moves like this are common during training camp as teams adjust to unexpected injuries.
4. Younger Linebackers Now Have Bigger Opportunities
The Demetrius Flannigan-Fowles injury could benefit several young players fighting for roster spots.
Buffalo’s linebacker competition now includes:
- Terrel Bernard
- Dorian Williams
- Joe Andreessen
- Kaleb Elarms-Orr
- Keonta Jenkins
- Otis Reese IV
Every preseason snap becomes even more important as coaches finalize the defensive depth chart.
Several young linebackers have already impressed during camp, and Buffalo will closely evaluate them over the next few weeks.
5. The Injury Affects Buffalo’s Depth More Than Its Starters
Although Flannigan-Fowles was not expected to start, losing an experienced veteran still matters.
NFL teams rely heavily on experienced backups during the long season, especially on special teams.
His absence places additional pressure on younger linebackers to prove they are ready for meaningful NFL snaps if injuries occur during the regular season.
The Bills hope their remaining depth can handle the increased workload while they await further updates.
What Happens Next?
Buffalo will continue evaluating its linebacker room throughout the preseason.
If Otis Reese IV performs well, he could strengthen his chances of making the final roster. Meanwhile, the Bills are expected to provide additional information on Flannigan-Fowles’ recovery if it becomes available.
For now, the Demetrius Flannigan-Fowles injury stands as another reminder of how quickly NFL training camp battles can change.
Buffalo will continue monitoring its linebacker depth throughout the preseason, while younger players battle for roster spots.
