The 49ers said Wednesday they’ve signed defensive lineman Quinton Dial to a three-year contract extension, one day after reaching a deal for a four-year extension with tight end Garrett Celek.
Earlier in the day, general manager Trent Baalke said the team was interested in locking in its young talent to longer deals, and Dial fits that description.
Dial, 25, a fifth-round pick in 2013, has started 21 games in the past two seasons. He and Arik Armstead, last year’s first-round draft pick, are expected to be the starting ends in the 49ers’ base 3-4 defense this year.
“Throughout his first three seasons in the NFL, Quinton has shown consistent development and has become a key contributor in our defense,” Baalke said in a statement. “We have certainly seen his positive impact on the field and in our locker room, but we also recognize the impressive work he does in the community year round. We are pleased to extend the contract of young players like Quinton and are excited to see him continue his career with the 49ers.”
Dial would have become a free agent after the 2017 season. He had career highs in tackles (73) and sacks (2.5) last year and also had two blocked field goals. But the 49ers’ defense was 29th in the NFL against the run, 29th in sacks and allowed a league-worst 20 rushing touchdowns.
