BUFFALO, N.Y. (AP) — The Bills'defensive front quickly took shape Tuesday, when Star Lotulelei agreed to sign with Buffalo, and Kyle Williams chose to return for a 13th season.
A person familiar with the situation confirmed to The Associated Press that Lotulelei reached an agreement to sign a five-year contract with the Bills. The person spoke on the condition of anonymity because the signing won't become official until the NFL's business year opens on Wednesday.
The agreement was first reported by ESPN.com.
A few hours later, the Bills announced they agreed to a one-year deal to re-sign Williams, who was contemplating retirement for a second consecutive offseason.
The moves bulk up Buffalo's defensive front by filling both tackle starting positions a day before the start of free agency.
Just as important, the Bills retain a steadying presence in their locker room in Williams after losing another key leader in center Eric Wood, who was diagnosed with a career-ending neck injury in January.
Williams was an unquestioned leader on a patchwork, rebuilding team that exceeded expectations with a 9-7 record and ended a 17-season playoff drought. The 34-year-old is so highly regarded, coach Sean McDermott would grow emotional in discussing what the player meant to the team.
"It's hard not to gravitate toward a guy like that, because of who he is as a person more so than anything," McDermott said of Williams in December. "How could you not like the way he plays and appreciate that, right?"
Williams returns to his familiar spot in the middle, which he's held since the Bills selected in the fifth-round of the 2006 draft. And he'll be playing alongside the 28-year-old Lotulelei, who takes over after Buffalo traded Marcell Dareus to Jacksonville in October.
Lotulelei was a five-year starter with Carolina after being selected by the Panthers in the first round of the 2013 draft out of Utah. The native of Tonga is listed at 6-foot-3 and 311 pounds, and fills an immediate hole on Buffalo's defensive front.
Lotulelei is reunited with McDermott, who was Panthers defensive coordinator before taking over in Buffalo in January 2017. Bills general manager Brandon Beane is also familiar with Lotulelei and played a role in drafting him after previously serving as Panthers assistant GM.
Lotulelei has forced two fumbles and has 11 1/2 sacks in 76 career games, and was voted to the NFL all-rookie team in 2013. His future in Carolina was uncertain after the Panthers signed defensive tackle Kawann Short to a five-year, $80 million contract extension last offseason, and also used a first-round pick for Vernon Butler last year.
Williams is a one-time All-Pro and five-time Pro Bowl selection. He showed no signs of slowing last year, with 41 tackles and three sacks in starting all 16 games. Overall, his 43 1/2 sacks are the most by a defensive tackle in franchise history.
Buffalo's defensive front seven has numerous needs with starting linebackers Preston Brown and Ramon Humber eligible to become free agents. The Bills finished 26th in yards allowed and gave up 140 or more yards rushing eight times, including a 10-3 loss to Jacksonville in the AFC wild-card playoff game.
Lotulelei's addition is the latest bold move made by Beane in reshaping Buffalo's roster since being hired in May to replace Doug Whaley.
Beane has already completed two trades over the past week in dealing quarterback Tyrod Taylor to Cleveland and sending starting offensive tackle Cordy Glenn to Cincinnati . Buffalo moved up nine spots in the first round by acquiring the Bengals' selection, 12th overall, as part of the Glenn trade.
The deals continued strengthening Buffalo's bid for selecting one of several highly regarded quarterback prospects in the first round next month. The Bills have two picks in each of the first three rounds, including the 22nd selection.
