Joe Flacco is healthy enough to play, but rookie Lamar Jackson will remain the starting quarterback. Jackson lost for the first time as a starter on Sunday against the Kansas City Chiefs. He was typically uneven as a passer, completing 13 of 24 for 147 yards. On the plus side, he got wide receivers Willie Snead, Michael Crabtree and John Brown more involved, connecting with them 10 times on a combined 17 targets. The Ravens have fallen to 18th in passing yards a game and 26th in yards an attempt.

The Ravens ran for 198 yards against the Chiefs, falling just short of clearing 200 for the fourth straight game. Gus Edwards started in Kansas City, but Kenneth Dixon was the story, carrying eight times for 59 yards and a touchdown in his second game back from injured reserve. Harbaugh said he expects Dixon to continue pushing for a greater role. Jackson has carried 67 times for 366 yards in four starts, a 1,464-yard pace over a full season.

The Ravens rank fourth in the league in run defense and have allowed opponents to average just 3.8 yards per attempt. They haven’t allowed an opponent to rush for 100 yards since Week 9. Linebacker C.J. Mosley leads them with 83 combined tackles, and defensive tackle Brandon Williams has lifted his performance over the last two games.

The Ravens hit Chiefs quarterback Patrick Mahomes 15 times on Sunday, with outside linebackers Matthew Judon, Terrell Suggs and Za’Darius Smith all delivering strong games. A groin injury limited cornerback Marlon Humphrey against the Chiefs and could bother him going forward. Slot cornerback Tavon Young is in the same boat. With both of them limited, Jimmy Smith played almost every snap and will have to carry a heavy workload going forward.

Justin Tucker has made 26 of 28 field-goal attempts, with his only misses coming on blocks. Sam Koch is tied for seventh in the league with 24 punts inside the opponent’s 20-yard line. Cyrus Jones increased his punt-return average to an impressive 16.1 yards when he broke a 55-yarder to set up a touchdown against the Chiefs.

The Ravens lost an overtime heartbreaker to the Chiefs but proved they could hang with one of the best teams in the league, on the road, with Jackson at quarterback. They’re in solid position to claim either the AFC North or the second AFC wild-card spot. Harbaugh said they’re proceeding as if they need to win their last three games to pull it off.

Quarterback Jameis Winston had to win his job back from Ryan Fitzpatrick but has started since Week 12 and thrown for six touchdowns against one interception in that three-game span.He regressed in a loss to the New Orleans Saints on Sunday, completing just 18 of 38 passes. Winston throws to one of the best and deepest receiver groups in the NFL. Mike Evans leads the way with 70 catches for 1,207 yards. DeSean Jackson has missed the last two games with a thumb injury.

The Buccaneers rely heavily on their passing game and rank just 27th in rushing yards per game and 30th in yards per attempt. Peyton Barber is their leading rusher with 677 yards but has averaged just 3.7 yards per attempt. Winston is a running threat, averaging 30.5 yards per game and 6 yards per attempt.

The Ravens get to face another weak run defense. The Buccaneers allow opponents to average 4.8 yards per carry, eighth-worst in the league. They’ve given up at least 100 yards eight games in a row. Veteran defensive tackle Gerald McCoy remains Tampa Bay’s best run defender. Linebacker Lavonte David leads the Buccaneers with 93 combined tackles, but his partners in the middle — Kwon Alexander and Adarius Taylor — have struggled.

The Buccaneers allow 7.3 yards per attempt, third-worst in the league. McCoy and Jason Pierre-Paul (11.5 sacks) remain formidable pass rushers, but cornerbacks Ryan Smith, Brent Grimes and Carlton Davis (who’s missed the last two games with a knee injury) have all been mediocre or worse in coverage. Tampa Bay lost its most talented cornerback, Vernon Hargreaves, to a torn labrum in his shoulder.

The Buccaneers have struggled here. Cairo Santos replaced Chandler Catanzaro as the team’s kicker in Week 11 and has made three of five attempts. Bryan Anger ranks 27th in net punting average and punts inside the opponent’s 20-yard line. The Buccaneers haven’t broken a punt return longer than 16 yards or a kick return longer than 29 yards on the season.

The Buccaneers fell out of realistic playoff contention with a four-game losing streak in October and November. They’re 1-5 on the road. But they’ve beaten good teams, including the Saints in Week 1, and have won two of their last three, suggesting they’ve hardly quit. Dirk Koetter often appears on lists of NFL coaches on the hot seat.
