Landry took a left knee from Jamal Lewis to the crown of his helmet and needed to be carted off the field in the final minute of the first half.
In the background, most of the Ravens took a knee on the field and prayed.
Before Landry's injury, the Ravens had allowed the Browns to move the ball quite easily.
After they lost their teammate, their tone changed.
"I think it all started with us losing Landry," Suggs said. "We were fired up."
So, how dominant was the Ravens' defense?
Down 10-7 at halftime, the Ravens needed only four plays from their offense in the third quarter to take a 21-10 advantage.
Over that suffocating 4 minutes, 37 seconds, the Browns managed 11 yards of total offense while the Ravens' defense recorded 44 yards on interception returns.
"We don't take any challenge lightly," McAlister said. "We figure they'll break if we keep breaking them."
The pressure applied by the Ravens' defense took some weight off their offense.
Rookie quarterback Joe Flacco (13-for-19 for 129yards and two interceptions) didn't need to make any big plays, and the Ravens could ride their running game (151 yards rushing) for most of the second half.
"Anytime you're on offense, you want to put points on the board," Flacco said. "As the game goes along, you realize that our defense helps us out a lot. If we can get better and capitalize more of our opportunities, we're going to be a pretty good team."
The Ravens improved to 2-0 - their same record in the AFC North - to set up a first-place battle with the Pittsburgh Steelers next Monday.
The loss was a devastating one for the Browns, whose playoff hopes might have dissolved in Week 3. The last team to start 0-3 and reach the playoffs was the 1998 Buffalo Bills.
"I think they expected to be 2-0," Harbaugh said of his team. "I think those players are exactly where they expected to be at this point."
