The Vikings were without two starting defensive linemen at today's practice.

Defensive end Everson Griffen, who sat out Sunday's win against the Chiefs due to an illness, was not yet ready to practice today. Coach Mike Zimmer said earlier that Griffen was "finishing up some tests" and Zimmer expected Griffen to be ready to practice by tomorrow if he couldn't make it today.

Defensive tackle Sharrif Floyd did not practice due to an ankle/knee injury. Floyd, presumably, suffered the injury Sunday, perhaps on the first-quarter play that probably should have been a safety. After the game, Floyd admitted to getting a little banged up there.

The only other Vikings player who wasn't practicing was reserve defensive end Justin Trattou, who hurt his foot in the Week 3 win over the Chargers.

Cornerback Terence Newman (ankle), right tackle T.J. Clemmings (knee), and running backs Adrian Peterson (finger) and Matt Asiata (rib) were listed as limited participants.

Cornerback Josh Robinson practiced for the first time today since spring workouts. He has been on the PUP list with a partially-torn pectoral. He said earlier today that he has not had a conversation with Zimmer and the medical staff about when he might be activated to the 53-man roster. Now that he has practiced, the Vikings have three weeks to make a move.

Finally, wide receiver Charles Johnson, who has missed two straight games with a rib injury, was a full participant today. He practiced on a limited basis all three days last week but did not play Sunday.
