BALTIMORE (AP) – Justin Tucker kicked a 47-yard field goal as time expired, and the Baltimore Ravens rallied from a 10-point deficit in the fourth quarter to beat the bumbling St. Louis Rams 16-13 Sunday.

In a game filled with mistakes and penalties, one final miscue decided the issue. Rams quarterback Case Keenum fumbled when hit by Courtney Upshaw, and teammate Lawrence Guy recovered at the St. Louis 41 with 54 seconds to go.

The Ravens (3-7) moved to the 29 before Tucker delivered the game-winning kick.

St. Louis (4-6) lost four fumbles and missed an extra point. In his first start of the season, Keenum went 12 for 26 for 136 yards and fumbled three times, losing two.

Baltimore won despite committing two turnovers and being penalized 10 times for 137 yards.

The Ravens trailed 13-3 before coming back behind Joe Flacco, who went 27 for 44 for 299 yards and a score.
