Still, there is something you can always count on from Flacco -- he's always going to suit up. Flacco made his 81st straight start in Thursday's season opener, surpassing linebacker Jarret Johnson for the longest regular-season streak in franchise history.
Flacco's durability is also making a dent in the NFL record books as well:
Flacco's streak stands as the ninth longest for quarterbacks in NFL history. Brett Favre owns the longest at 321 games. Just counting the regular season, it would take Flacco 14 more seasons to catch Favre. Flacco is seven more starts away from surpassing Dan Marino for No. 8 on the list.
Flacco has started more consecutive games than any other quarterback in Baltimore's NFL history. He moved past Johnny Unitas (91 straight starts from 1959 to 1965) when he started the AFC Championship Game in New England in January.
"I’m definitely proud that I can say that I’m there for my team every Sunday," Flacco said earlier this summer. "It’s not about being hurt, not being hurt. It’s about being durable. As a player and as a quarterback, there really is only one of you on every Sunday. You just take pride in that you can show up for your teammates. You hopefully give the best performance that you can give each and every week. I definitely think that helps out a lot just in terms of being a leader on a team, as all the other guys can trust that you’ll be out there for them.”
To put this in perspective, the Browns, who are playing the Ravens on Sunday, have had nine starting quarterbacks during Flacco's streak: Derek Anderson, Brady Quinn, Ken Dorsey, Bruce Gradkowski, Jake Delhomme, Colt McCoy, Seneca Wallace, Brandon Weeden and Thad Lewis.
