Vikings place Jordan Mason on injured reserve with fractured thumb

Key Points:

• Minnesota Vikings running back Jordan Mason has been placed on injured reserve due to a fractured thumb, which head coach Kevin O'Connell described as a "small" fracture that has been fixed; Mason will miss at least four games.
• Mason, a co-starter who shared backfield duties with Aaron Jones, led the team with 15 carries for 59 yards and a touchdown in the recent win over the Green Bay Packers.
• The Vikings are also dealing with quarterback injuries, as starter Kyler Murray remains in concussion protocol, with backup Carson Wentz expected to start until Murray returns.
• To compensate for Mason's absence, the Vikings promoted running back DeeJay Dallas from the practice squad to the active roster and added Jerome Ford to the practice squad; Dallas will compete for playing time alongside rookie Demond Claiborne.
• Mason's injury is a setback for the Vikings' offense, which showed promise in their comeback victory over the Packers, relying heavily on the effective running back duo of Mason and Jones.
