First, it was migraines. Now a hip injury threatens to sideline Vikings WR Percy Harvin.
After being limited in practice Wednesday by the ailment, on which the Vikings have not elaborated, Harvin did not participate in practice at all Thursday.
With leading WR Sidney Rice out until midseason following hip surgery in August, the Vikings would have to rely on Bernard Berrian, Greg Lewis and recently acquired Greg Camarillo at wideout if Harvin can't go Sunday against Miami.
The team is a potential suitor for Chargers holdout WR Vincent Jackson, who is on the trade market.
Meanwhile, CBs Cedric Griffin and Chris Cook are closer to returning to action after having missed the opener at New Orleans. Both players had limited participation in practice Thursday.
