Diggs sat out practice on Tuesday and Wednesday while nursing a knee injury.
If the second-year pro can’t go, it would be a big blow to the Vikings passing game against a Lions defense that has allowed a 108.5 passer rating (highest in the NFL) and 73 percent of throws to be completed.
Sans Diggs, Adam Thielen would see a boost in targets and Cordarrelle Patterson would likely play a bigger role in the every-down offense. Also expect a big day from Kyle Rudolph against a Detroit team that struggles to cover tight ends. If Diggs plays on Thanksgiving he’ll be less than 100 percent, but would have a good matchup against Detroit’s slot corners.
Minnesota also listed safety Harrison Smith, linebacker Eric Kendricks and corner Captain Munnerlyn as questionable. Veteran corner Terence Newman is listed as doubtful. Corner Marcus Sherels and defensive tackle Sharrif Floyd were both ruled out.
