With the Ravens trailing by a touchdown late in the fourth quarter in Denver, majority owner Steve Bisciotti wrote a text message to Harbaugh.
Dealing with the flu, Bisciotti wasn't able to attend the game.
"I've never texted you during a game," said Harbaugh in the locker room afterward with cameras capturing him reading the text to the players. "We are down 35-28. And I think it's the best game I've ever seen us in the playoffs since 2000. Win or lose, I am so proud of the team and proud of you."
The Ravens won the game behind a 70-yard game-tying touchdown catch by wide receiver Jacoby Jones and a 47-yard game-winning field goal by kicker Justin Tucker in overtime.
"I'm not going to say on his deathbed, but he was really sick," Harbaugh said. "He couldn't get up and move around at all. ... It was just something I thought the team needed to hear coming from him. He's a great leader. Our players love him. They love when he's around.
"He's an inspiration to all our guys. This organization, he sets the tone here. It's a great organization because of his vision. The guys needed to hear that in that moment. I think they appreciated hearing it."
--Although it wasn't quite a vintage performance for Terrell Suggs, the former NFL Defensive Player of the Year arguably turned in his best performance since returning from a partially torn Achilles tendon.
Despite his torn right biceps, Suggs repeatedly bull-rushed standout offensive tackle Ryan Clady into the backfield.
Suggs finished with a season-high 10 tackles, two sacks, one for a loss and a pass deflection when he dropped back into coverage.
Even though Suggs obviously still isn't 100 percent, it was his strongest game since returning in October against the Houston Texans from an Achilles injury that required surgery.
----Pulling to his left during the third quarter of the Ravens' 38-35 double-overtime victory over the Denver Broncos, offensive guard Marshal Yanda quickly gained momentum before crashing into linebacker Wesley Woodyard with his left shoulder.
The block created a big hole for Pro Bowl running back Ray Rice up the middle on his 32-yard run that set up his one-yard touchdown run three plays later.
"It was a heck of a block," coach John Harbaugh said. "That's just how Marshal does it."
Named to the Pro Bowl for the second consecutive year, Yanda is known for his hard-nosed approach to the game.
"It was a one-back power play," Yanda said. "It was a great double-team by (left offensive guard Kelechi Osemele) and (left offensive tackle Bryant McKinnie). When they have a good double-team, there's really no place for the linebacker to go to fill that hole, and it makes it easy for me to run around there and pull tight and kick him out and Ray hits it."
