John Vaughn, filling in for All-Pro Rob Bironas, kicked a 33-yard field goal as time expired Friday night to lift the Titans to a 17-16 victory over the Raiders in an exhibition featuring the first quarterbacks taken in the 2006 and 2007 drafts. Oakland (1-1) appeared set to remain unbeaten as Aaron Elling, subbing for an injured Sebastian Janikowski, kicked three field goals with the last one bouncing off the left upright with 5:19 left to put the Raiders ahead. But undrafted rookie safety Tony Joyner knocked the ball away from Oren O'Neal at the Titans 1 with 2:10 left, and rookie Stanford Keglar recovered for Tennessee (2-0). Ingle Martin, a Nashville native, was 6-of-8 on the drive and set up the winning field goal with a 26-yard pass to Chris Davis. Darren McFadden, the first running back taken in the draft at No. 4 by Oakland, ran six times for 44 yards. Tennessee's Chris Johnson, the fifth running back drafted at No. 24 overall, picked up 46 yards on eight carries and returned a kickoff 30 yards. Johnson stunned fans a week ago with a 66-yard TD run, and he picked up 15 yards on each of his first two carries against the Raiders.
