San Diego's offensive line is being challenged

Posted by ESPN.com’s Bill Williamson

SAN DIEGO -- The Ravens’ pass rush is starting to wear down San Diego’s makeshift offensive line.

The pressure is becoming constant. A Ray Lewis blitz just caused San Diego quarterback Philip Rivers to make a terrible play. Rivers tried to get rid of the ball instead of taking a sack deep in his own territory. But the ball was intercepted and the Ravens took over at the San Diego 30.

The Ravens took advantage of the miscue and scored a touchdown. They now lead 28-16.

Son Diego is now in catch-up mode. But it will have a difficult time passing the ball if the Ravens continues to harass Rivers. San Diego is playing without center Nick Hardwick (ankle) and guard Louis Vasquez (knee).
