Dalvin Cook underwent surgery Tuesday to repair a shoulder injury that the Minnesota Vikings said was "sustained over the past few seasons."

The Vikings called the surgery "successful" and said Cook "is expected to make a full recovery prior to the start of the regular season."

Cook has dealt with chronic shoulder injuries dating back to his time at Florida State. A 2019 injury, which was reported was a "broken shoulder," forced him to miss the final two games of that season. A related injury forced him to miss some time in 2021 as well.

Justin Jefferson has been named the 2022 NFL Offensive Player of the Year.

Jefferson caught 128 passes for 1,809 yards and eight touchdowns.

The Minnesota Vikings have hired Brian Flores as defensive coordinator, replacing Ed Donatell in the position.

Flores spent last season as the Pittsburgh Steelers' senior defensive assistant/linebackers coach after being fired as head coach by the Miami Dolphins following the 2021 season. 

Flores was also a finalist for the Arizona Cardinals' head coaching position.
