The Ravens' starters will see their most extensive action of the preseason, operating under the traditional third-game format Thursday night against the Jacksonville Jaguars at M&T Bank Stadium.

Although some players won't play all the way into the third quarter, coach John Harbaugh indicated that the majority of the starters will be used that way.

"It's going to be like a third-game format, which is usually a three-quarter format," Harbaugh said following practice Tuesday at the Ravens' training complex. "We'll just kind of work back from there with guys as far as how many reps they get. We'd like to see them get a lot of good extended work."

Most of the Ravens' starters won't play much, if at all, during the preseason finale against the St. Louis Rams.

So, this represents the final chance for the first-team offense and first-team defense to build timing in a game situation prior to the Sept. 10 regular season opener against the Cincinnati Bengals.

The Ravens (1-1) lost to the Jaguars, 12-7, during a nationally televised game last season as running back Ray Rice was limited to 28 yards on only eight carries, and quarterback Joe Flacco completed just 21 of 38 passes for 137 yards.

"I think we're looking at it as a good test for us and just another opportunity for us to go out there and work on what we've been working on all training camp and go out there and be successful at it," Flacco said when asked about facing the Jaguars again. "We've been having a great time out here and working hard, so we want to go out there and put our best foot forward and just have a good outing."
