Last Meeting ( Aug 29, 2013 ) Baltimore 21, St. Louis 24

The Baltimore Ravens were informed by the NFL on Monday that an officiating mistake led to their loss to the Jacksonville Jaguars last week, marking the latest in a series of tough setbacks for the team this season. The Ravens will try to put it behind them and earn a third victory when they host the St. Louis Rams on Sunday.

The Ravens were hit with a facemask penalty on the final play of the game, leading to a down that allowed Jacksonville to kick the game-winning field goal in a 22-20 decision, but a false start that would have resulted in a 10-second runoff should have ended the game prior to the facemask. "Part of the game is human error," Baltimore quarterback Joe Flacco told reporters. "Once the game is over, man, it's over. There's no going back and changing that.” The Rams are coming off back-to-back losses that dropped the team below .500, and defensive end William Hayes summed up the team’s mindset. “No, it’s not time to panic," Hayes told reporters. "It’s time to just fix (stuff). We have got to go out there and play better football (this) week.”

ABOUT THE RAMS (4-5): The one big change for St. Louis this week is at quarterback, where Case Keenum will take over for an ineffective Nick Foles. Keenum made 10 appearances for the Houston Texans in 2013 and 2014, and doesn’t have a high bar to clear with the Rams after Foles totaled one TD pass in the last four games. "You have to be ready when you get a chance,” Keenum told reporters. “I'm ready. I've been prepared and that's what I do every week, is I get ready to play. I'm excited for my chance, I really am. I'm excited to go out there and compete again.”

ABOUT THE RAVENS (2-7): Baltimore has its own issues at quarterback, though Joe Flacco is in no immediate danger of losing his job. The veteran was intercepted twice and lost a fumble last week to bring his turnover total to 12, tied for fourth among QBs. "Maybe they weren't all bad decisions, but I would say that I've probably made more bad decisions, and that’s why there's a little bit more of them," Flacco told reporters. "It comes down to game day and reacting, playing within yourself. I probably haven’t done that as well as I have in the past."

EXTRA POINTS

1. Ravens rookie WR Breshad Perriman was placed on IR this week because of a knee injury that has kept him out the entire season.

2. Keenum quarterbacked the Texans to a 25-13 victory over Baltimore on Dec. 21, 2014.

3. St. Louis DE Chris Long (knee) could play for the first time since Oct. 11.
