The person, who spoke to The Associated Press on condition of anonymity on Thursday because the Vikings were not releasing details about Smith’s status, said the 36-year-old would be evaluated weekly for his return from an absence that is not expected to be long term. Smith, who has started his 14th season in the NFL, was elected by Vikings players as one of eight team captains this year. Smith was last seen at practice that was open to reporters on Aug. 11. The Vikings open the regular season on Sept. 8 with an NFC North division game at Chicago.
