Here are some observations from the open periods of practice:Tory Blaylock Back Dressed OutAfter heading off the field with the injured players in last week's open practice, sophomore running back Tory Blaylock remained on the field and dressed out Tuesday. Blaylock was not a full participant, though, spending plenty of the drills running half speed or off to the side. Hopefully their absence was primarily precautionary but tackle Michael Fasusi and guard Heath Ozaeta headed toward the injured players tent when practice began. Michael Boganowski Held up as ExampleOklahoma wide receivers coach Emmett Jones repeatedly brought up safety Michael Boganowski any time his players showed sloppy execution on a drill. He had several drops, but also showed plenty of explosiveness and agility, standing out amongst the position group.
