Jets Confidential reports that the doctors gave QB Vinny Testaverde a positive diagnosis today, but he still might miss the first preseason game vs. the Steelers. Both LB Sam Cowart and WR Laveranues Coles missed the morning practice. OG Randy Thomas and C Kevin Mawae practice without pads and only in non-contact drills. OG David Viger is out for one month. QB Chad Pennington and CB Ray Mickens have both looked impressive.
