MINNEAPOLIS -- Wide receiver Percy Harvin and middle linebacker E.J. Henderson suited up for Minnesota after being listed as questionable for Sunday's game against San Francisco.
Harvin sat out Thursday and Friday because of an illness. Henderson was limited in practice due to a shoulder injury.
The NFC's top two rushers, Minnesota's Adrian Peterson (back) and San Francisco's Frank Gore (ankle), were also in their respective lineups after being listed as probable.
The Vikings designated Sage Rosenfels as the third quarterback.
The 49ers had backup linebacker Marques Harris (toe) on their inactive list.
