The Vikings re-signed center Brett Jones to a one-year contract Monday.

Jones, 27, was acquired in a trade from the Giants for a 2019 seventh-round draft choice in August and played in 14 games for the Vikings, including three starts at center while Pat Elflein recovered from injuries.

A native of Saskatchewan, Jones won a Grey Cup with Calgary in 2014 and was the Canadian Football League’s most outstanding lineman that season, after which he signed with the Giants.

The 6-2, 310-pound Jones started 14 of his 30 games with the Giants from 2015-17. He made $2.914 million last season, but his deal for 2019 has a base salary of $850,000.
