The Minnesota Vikings opened the 21-day practice window Wednesday for center Ryan Kelly, who was placed on injured reserve after suffering two concussions in the first month of the season.
Kelly, 32, started the first two games this season before missing Week 3 in concussion protocol. He returned to the starting lineup in Week 4 but was back in the protocol and placed on injured reserve on Oct. 4.
A four-time Pro Bowl selection during nine seasons with the Indianapolis Colts (2016-24), Kelly signed a two-year, $18 million deal with Minnesota in March.
Kelly has made 124 career starts since the Colts drafted him with the 18th overall pick in 2016.
