The Bills announced a couple of roster moves on Monday.
They have signed wide receiver Mac Dalena to their 90-man roster. Cornerback Daryl Porter was waived in a corresponding move.
Dalena signed with the Chiefs after going undrafted last year and had two catches in the preseason before getting cut in August. He spent time on the Seahawks’ practice squad and was on the Jets’ roster this offseason.
Dalena had 126 catches, 1,761 receiving yards and 13 touchdowns while at Fresno State.
Porter was also undrafted in 2025. He signed with the Bills and spent time with the Steelers before returning to Buffalo.
WIde receiver DJ Moore is in his first offseason with the Bills and adjusting to the team’s offense remains a work in progress.
The Bills acquired Moore in a trade with the Bears in March and he’s had his first chance to work with quarterback Josh Allen over the last few weeks. Their connection and Moore’s overall fit in the Buffalo offense is still coming together, but he said this week that he expects it to be in great shape down the road.
“It’s going good,” Moore said, via Katherine Fitzgerald of the Buffalo News. “I mean, it’s gonna be perfect later on, but right now it’s still growing pains.”
Allen had positive things to say this month how Moore is acclimating to life with the Bills and Moore said he’s been impressed by just how fast [Allen] can just dial it up throughout the week and pick up new things.” The Bills will be banking on that leading to a potent connection come the fall.
Veteran edge rusher Joey Bosa is one of the top players remaining on the free agent market.
The question is: Does he want to continue his career? If he does, Bosa will have options.
His brother, 49ers edge rusher Nick Bosa, seems to have doubts about how much Joey Bosa wants to play an 11th season.
“I think he’s working on his golf game right now,” Nick Bosa said Thursday, via David Bonilla of 49erswebzone.com. “So, I don’t think he’s thinking too much about football.”
The 49ers finished with an NFL-low 20 sacks last season, with Nick Bosa tearing the ACL in his right knee in Week 3. Nick Bosa is back, and Kyle Shanahan addressed whether Joey Bosa might join his brother in San Francisco this season.
“I look at our team as kind of we have our team, and anyone else that we can figure out to bring, especially someone like that, that would be awesome,” Shanahan said. “But that stuff’s not always possible.”
Joey Bosa, who turns 31 in July, has not had a double-digit sack season since 2021. The five-time Pro Bowler has only 19 across the past four seasons, including five in 2025.
The Bills signed inside linebacker Demetrius Flannigan-Fowles to a one-year deal on Wednesday, the team announced.
Flannigan-Fowles joins the team in the middle of their organized team activities.
He played for the Giants during the 2025 season, appearing in 10 games with three starts. Flannigan-Fowles spent the first five seasons of his NFL career with the 49ers.
He played 73 games with seven starts with San Francisco, registering 96 tackles, six tackles for loss, one interception and one sack.
Flannigan-Fowles entered the NFL as an undrafted free agent in 2019 out of Arizona.
In a corresponding move, Buffalo released wide receiver Max Tomczak.
The Bills are installing a new defense after this offseason’s coaching change, but one player will remain a central part of the plans in Buffalo.
Defensive tackle Ed Oliver has been a vital piece of the defense for several years and new defensive coordinator Jim Leonhard views him the same way. Leonhard plans to tweak the way that Oliver is deployed, however, and he believes it will make for even more production up front.
“I think Ed’s going to be really disruptive in this defense, the base defense being more different for him than what it’s been in the past and, in all reality, a little more freedom than he’s had in the past,” Leonhard said, via Tim Graham of TheAthletic.com.
Oliver said that he has watched how the Broncos used Zach Allen — Leonhard was on Denver’s staff the last two years — and called it “definitely exciting” to think about having the same kind of success this season. If that happens and Oliver can stay healthy after missing 14 games last season, the Bills’ defensive transition should be in good shape.
