The Baltimore Ravens and NFL have hit a snag in trying to schedule the annual midweek season opener typically awarded to the defending Super Bowl champions.

The problem?

The Baltimore Orioles are scheduled to host the Chicago White Sox on Thursday, Sept. 5, at Oriole Park at Camden Yards. The baseball stadium shares parking lots with the Ravens' M&T Bank Stadium, making it impossible for both sites to host games simultaneously.

And a Major League Baseball official told USA TODAY Sports she isn't optimistic the Ravens can be accommodated.

The 2012 regular season kicked off with the New York Giants hosting the Dallas Cowboys on a Wednesday night at MetLife Stadium in New Jersey so as not to conflict with the final night of the Democratic National Convention. Wednesday is not an option in 2013, an NFL spokesman said, because of an overlap with the Jewish holiday, Rosh Hashanah.

"We have had discussions with representatives of the Orioles, and we have offered to make them financially whole," Ravens president Dick Cass said in a statement posted on the team's Twitter account Monday afternoon. "We've left it there. Now the commissioner is trying to find if he can find a solution."

But Katy Feeney, Major League Baseball's senior vice president, schedule and club relations, doesn't sound like MLB will budge.

"You never say never but it is going to be difficult to change the schedule on that day," Feeney told USA TODAY Sports. "From a competitive standpoint, it will be late in the season, both teams could be in playoff contention, and it's a lot to ask two teams that are getting in during the wee hours of the morning following night games to turn around a play a day game.

"From a revenue standpoint, a day game versus a night game during a weekday also makes a difference, both as far as the potential impact on attendance and the (advertising) revenue from both teams' broadcasts. I've spoken to the NFL and I believe both commissioners have spoken. We have a good relationship with the NFL, but we also have to do what is best for our clubs."

Ravens owner Steve Bisciotti weighed in on Twitter, adding: "I think there's an opportunity here for MLB and the NFL, who have to get along and accommodate each other at times."

NFL Commissioner Roger Goodell said Monday at the NFL league meetings in Phoenix that he has been in touch with the Orioles. When asked for comment by USA TODAY Sports, an Orioles spokesman directed inquiries to Feeney.

The home and away opponents for each NFL team were set at the end of last season, but the league's schedule makers are still in the process of finalizing the 17-week regular season. The full schedule is typically released in mid April, about a week prior to the draft.

The Ravens will host each of the teams in the AFC North as well as the New York Jets, New England Patriots, Houston Texans, Green Bay Packers and Minnesota Vikings.

Goodell said making the Ravens play their first game on the road is a last resort, saying: "We think that's wrong for Ravens fans, that's why we're trying to work on an accommodation."
