If the officials had run to the line of scrimmage and stopped the play before Suggs' penalty, the Titans would have been assessed a 5-yard penalty and would have faced third-and-15 at their 15-yard line.
"No, I did not hear a whistle on that play," Ravens defensive tackle Haloti Ngata said.
Asked whether he saw the officials try to stop the play, Ngata said: "No. I didn't even know."
The Ravens' demise was more shocking because of their domination over the first three quarters.
Three times, the Titans started in Ravens territory. But the Ravens held Tennessee to a field goal.
In building a 10-3 lead, the Ravens didn't allow a drive longer than 37 yards.
But the Titans went 81 yards on 13 plays before getting a 26-yard field goal by Rob Bironas early in the fourth quarter.
Then, aided by two Ravens penalties - Suggs' controversial roughing the passer and having 12 men on the field - Tennessee drove 80 yards on 11 plays.
Using a three-step drop to avoid the Ravens' pressure, Collins completed passes of 9, 10, 4, 13, 15 and 11 yards on the critical series to keep Tennessee undefeated at 5-0.
It marked only the third touchdown surrendered by the Ravens' defense in four games this season.
"We just waited to the last second to have our worst drive of the day," linebacker Jarret Johnson said. "It's a tough way to lose a game."
This isn't the Ravens' first conflict with officials.
During a 21-penalty game in Detroit three seasons ago, Suggs had a face-to-face argument with a referee after a roughing-the-passer penalty and was ejected.
Last season against the New England Patriots, linebacker Bart Scott was fined $25,000 for verbally abusing game officials and throwing an official's flag into the stands near the end of the Ravens' 27-24 loss.
Asked whether officials look at the Ravens closer than other teams, Suggs said: "Definitely. We're the bad boys of football. They're always going to look at us like that because of the physical style of football that we play. They're always going to have that close eye on us."
Now, after losing two games by a combined six points, the Ravens' defense must buckle down for a showdown with Peyton Manning and the Indianapolis Colts.
"We got 12 games left. This [loss to Tennessee] is not going to make or break us," Suggs said. "We can't hang on this. We're worried about the next game."
The penalty callThe Baltimore Sun's Jamison Hensley, the game's pool reporter, talked to referee Bill Carollo (right) after the game about Terrell Suggs' roughing-the-passer penalty during the Titans' game-winning drive. Here are Carollo's responses and Suggs' reaction:
The penalty: "On the play with about five minutes left, we had a false start on the offensive tackle No.71 [Michael Roos]. It was right at the snap. We tried to shut it down and blow the whistle. But the players didn't hear the whistle and they continued to play. [Terrell Suggs] came in and hit the quarterback on the side of the helmet. If it had been anything other than a personal foul, we would have disregarded [it]. But any 15-yard penalty - coupled with a false start - it's called a 'five and 15,' which means the 5-yard penalty is ignored and the 15-yard penalty is enforced from the previous spot."
Roughing the passer interpretation: "He got him on the side of the helmet, the right side of the helmet. We're blowing the whistle. ... He may not have heard that - and we're going to give him that - but he still can't hit the quarterback on the helmet."
Who threw the flag? "That was the referee. That was myself."
Suggs' reaction: "If anybody can go back and show me something I did illegal, then I would be happy to oblige and say I messed up. But when you are nowhere near his head - we hit arms, we hit arms - it just goes to show the referee has too much power in the game."
