The Dallas Cowboys' playoff chances have taken a devastating downhill drop following their 34-26 loss to the Minnesota Vikings.

FRISCO — Cowboys owner Jerry Jones said cornerback Trevon Diggs isn’t healthy enough to be activated off injured reserve. Diggs, meanwhile, said he’s healthy and ready to play after missing the last eight games with a head and leg injury, including Sunday night’s game against the Vikings — a game that Diggs said last week he expected to play in.
