(AP) — Assured at least a split in consecutive road games, the Oakland Raiders learned in a trip to Tennessee that their high-flying offense isn't as great as they may have thought. The Raiders found themselves shut out in the second half Sunday as they needed the defense to preserve a 17-10 win over the Titans, and Derek Carr said he was praying on the sideline that the defense would get a stop after a sloppy game by the offense. The Titans (1-2) will be poring over the tape checking the penalties called — and not called — on their final drive, when Tennessee thought it had a chance to force overtime. The Titans had the most costly with wide receiver Andre Johnson called for offensive pass interference, wiping out a 13-yard TD catch that would have allowed Tennessee to tie it up at 17 with 22 seconds left. The Raiders forced three turnovers and managed only one field goal off a fumble by Marcus Mariota. [...] left tackle Donald Penn was flagged for holding, forcing the Raiders to settle for a field goal by Janikowski. The 17-year veteran connected from 52 yards out, making him the NFL's all-time leader in field goals from 50 yards out or longer.
