With 14:19 to go in the contest, Tucker hooked a 37-yard field goal wide left, snapping his streak of 33 consecutive makes, which was the longest active run in the NFL.
Tucker hadn't missed a field goal since going 0-for-2 against the Browns in Week 2, and last week earned multiple honors for a 6-for-6 performance that included a game-winning 61-yarder at the Lions.
The second-year kicker is now 35-for-38 on the season, and the Ravens still trail the Patriots 20-0 in the fourth quarter.
Update: The Ravens are finally on the board with 9:21 to go, and it is a touchdown, their first since the last offensive play of the win over the Vikings two weeks ago.
Baltimore went 90 yards in nine plays and 2:48 with Joe Flacco providing the scoring dive, a 1-yard keeper that cut the Patriots' lead to 20-7.
The Ravens benefited from a successful challenge and two New England penalties on the drive, the last being a helpful 23-yard pass interference call that advanced Baltimore to the Pats' 2. The challenge overturned an incomplete ruling on a 15-yard pass where Dennis Pitta dragged his second foot inbounds.
So this one isn't over quite yet.
Update II: Now it's pretty safe to consider this one over. An unnecessary roughness penalty on Lardarius Webb was followed immediately by a 7-yard touchdown run by LeGarrette Blount, and the Patriots lead 27-7 with 2:05 to go.
The Ravens are actually outgaining the Patriots 308-300, but New England ran out to the early lead and Baltimore's offense never could get it going.
The Ravens have been playing four downs pretty much the entire second half, which has helped account for the yards total. But they haven't been in this contest from the start.
The Chargers just wrapped up a 26-13 win over the Raiders, so couple that with what is about to become the Ravens' seventh loss of the season and Baltimore will need some help to get into the postseason.

Update III: New England added another two touchdowns on a fumbled snap by Tyrod Taylor recovered by Chandler Jones in the end zone, increasing its lead to 34-7, and a pick-six, which upped the advantage to 41-7.
Forty more seconds and this one's mercifully over for the Ravens.
Update IV: This one's over. The Ravens lose 41-7 to slip to 8-7. More to come.
