SERIES: 7th regular-season meeting. Ravens trail series, 5-1. The Ravens have lost all four regular-season meetings in Miami. Last season, the Ravens lost, 22-16, in overtime to the previously winless Dolphins. Three plays after Ravens kicker Matt Stover hooked a potential game-winning field-goal attempt, little-known Miami receiver Greg Camarillo caught a short pass over the middle and out-sprinted the defense for a game-winning, 64-yard touchdown.
KEYS TO THE GAME: Ravens QB Joe Flacco is in a precarious position. The rookie has thrown five interceptions the past two games, but through the air is the best way to attack the Dolphins. Baltimore's young offensive line is suffering through several injuries while also preparing for a complex 3-4 scheme. That means Flacco can't count on help in the form of a consistent running game, while he's also likely to face pressure quickly on passing downs. ... Despite a rough outing in Indianapolis last Sunday, Baltimore still leads the NFL in rushing, passing and total defense. This will be the Ravens' first look at the 'Wildcat' formation, which the Dolphins add new wrinkles to each week. Baltimore is focusing on making sure all skill players are accounted for regardless of formation. The Dolphins know they must run the ball because the Ravens' pass rush will wreak havoc if able to pin its ears back and come after QB Chad Pennington.
KEY INJURIES: Ravens: LT Jared Gaither (knee) should start; RT Adam Terry (knee) is likely out; RG Marshall Yanda (knee) is out for the season, replaced by Chris Chester. Dolphins: CB Will Allen (knee) is expected to play.
FAST FACTS: Ravens MLB Ray Lewis has averaged 13.4 tackles in five career games against Miami. ... Pennington is the first Dolphins quarterback with three straight 100-plus passer ratings since Dan Marino in 1994.
-- RB Willis McGahee loves playing on his old stomping grounds. In four trips to Miami, he has averaged 91.7 yards rushing, including 104 yards last season.
-- FS Ed Reed was added to the injury report Thursday with a hamstring injury. It's hard to envision Reed being sidelined after starting 42 straight games. If Reed is out, he would likely be replaced by Tom Zbikowski or Haruki Nakamura.
-- OT Adam Terry missed his second straight day of practice with a right knee injury and is likely out. He will be replaced by Willie Anderson at right tackle.
-- WR Demetrius Williams was limited in practice Thursday after missing Wednesday with a knee injury. He is slow to rebound from injuries, so he would be limited even if he plays. Marcus Smith could move into the Ravens' No. 3 role.
-- CB Andre' Goodman was excused from practice Thursday to tend to a serious personal problem. He is expected to play Sunday.
-- CB Will Allen has been limping around the locker room all week with a sore left knee, but practiced and is expected to play.
-- FB Casey Cramer has a sore ankle and hasn't practiced all week. He isn't expected to play.
-- FB Lousaka Polite was signed Thursday to take Casey Cramer's place. Because he played for Tony Sparano and Bill Parcells in Dallas, he's familiar with their offensive system and could be activated Sunday. If not, Miami will use three tight ends: Anthony Fasano, David Martin and Joey Haynos.
-- T Kirk Barton was waived Thursday to make room for FB Lousaka Polite. Barton was signed last month but wasn't active in any of the three games he was here for.
