Coming off a 23-16 win against the Houston Texans on "Monday Night Football" Nov. 27, the Ravens (6-5) look to retain their grip on the sixth and final playoff spot in the AFC when they host the Detroit Lions (6-5) at M&T Bank Stadium Dec. 3.
The Lions have one of the league's highest-scoring offenses, averaging 26.7 points a game, and they rank second in the league in pass plays of 40 yards or more with 10. The Ravens, by contrast, rank 18th in the league in scoring (21.5) and last in the league in total offense, but seventh in total defense.
Here are some other key numbers for this week's game as the Ravens try to win three in a row for the first time this season and remain perfect at home against the Lions. (The teams have met here just twice, with the Ravens winning 19-10 in 2008 and 48-3 in 2009.)
0: Catches by Breshad Perriman against Houston after being a healthy scratch for the first time in his career a week earlier. Head coach John Harbaugh said the Ravens hoped to make Perriman's speed part of the game plan against Houston, but he had just two targets.
2: Seasons that Ravens offensive coordinator Marty Mornhinweg was the Lions head coach. Mornhinweg went 5-27 from 2001-2002 with the Lions.
4: Career completions thrown by punter Sam Koch, who tossed a 22-yard pass to Chris Moore on a fake punt to set up the Ravens' first touchdown against Houston. Koch, who threw a 16-yard pass to Moore against the Tennessee Titans in Week 9, is 4-for-4 for 48 yards as a passer in his career.
6: Seasons Perriman's father, Brett, played for the Lions. Brett Perriman broke into the league as a second-round draft pick by the New Orleans Saints in 1988, then moved to the Lions in 1991. Perriman had the most productive season of his career with the Lions, with 108 catches for 1,488 yards and nine touchdown catches in 1995.
7: Tackles this season for Detroit defensive tackle Haloti Ngata, who is in his third season with the Lions after playing nine years with the Ravens. Ngata started the first five games this season for the Lions but is on injured reserve with a biceps injury.
26: Takeaways by the Ravens this season, which leads the league. The Ravens got three takeaways against the Texans, with Tony Jefferson and Anthony Levine intercepting passes and C.J. Mosley recovering a strip-sack fumble caused by Terrell Suggs. The Ravens' turnover margin of plus-11 is also best in the league.
29: Punts inside the 20-yard line this season for Koch, which leads the league. Koch was named the AFC Special Teams Player of the Week this past week after averaging 51.3 yards on six punts, with five inside the 20, and throwing a 22-yard completion on a fake punt.
61: Length, in yards, of the field goal Justin Tucker hit against Detroit in 2013 to give the Ravens an 18-16 win. That is the longest in Ravens history. Tucker was responsible for all the Ravens' scoring in that game with six field goals, another team record.
64.3: Average yards rushing allowed by the Ravens during their past four games. With Brandon Williams back from injury and Willie Henry emerging as a force, the Ravens' run defense has overcome its early season woes. The Ravens this week face a Lions offense that ranks 30th in the league in rushing, averaging 78.3 yards a game.
124: Career sacks for Suggs, who had two of them -- including a key fourth-quarter strip-sack -- during the Ravens' 23-16 win against the Texans. Suggs, 35, leads the Ravens with 9.5 sacks. "He's Ponce de Leon -- you should put that on the back of his jersey," Harbaugh said after the Texans game. "He has found the Fountain of Youth. He's playing as well, or better, than I've seen him ever play since I have been here."
