INDIANAPOLIS –- The 49ers on Wednesday signed defensive tackle Quinton Dial to a three-year extension, preventing him from potentially becoming an unrestricted free agent next offseason.

Dial’s contract runs through the 2019 season, the 49ers announced.

According to the NFL Network, the deal is worth $12 million, including just over $5 million guaranteed.

"Throughout his first three seasons in the NFL, Quinton has shown consistent development and has become a key contributor in our defense,” 49ers general manager Trent 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, a fifth-round pick from Alabama in 2013, started 15 games at right defensive tackle last season. He finished fifth on the team with 73 tackles.

He also recorded 2 ½ sacks.
