CHICAGO -- Following two days of meetings, the BCS commissioners continued to inch toward deciding college football's playoff format for 2014.

Nothing of significance was determined Wednesday, but Pac-12 commissioner Larry Scott said different "options, plural" would be presented to the Presidential Oversight Committee on June 26.

The 11 FBS commissioners and Notre Dame athletic director Jack Swarbrick return to Chicago again next Wednesday in what was supposed to be the final meeting to determine how college football's playoff will look beginning in 2014.

Numerous commissioners, however, told CBSSports.com that there is a real concern that the group will not have settled on which playoff formats to go forward with on June 20.

The BCS issued a statement following Wednesday's meeting at the Chicago O'Hare Hilton.

"We made progress in our meeting today to discuss the future of college football's post-season. We are approaching consensus on many issues and we recognize there are also several issues that require additional conversations at both the commissioner and university president levels.

"We are determined to build upon our successes and create a structure that further grows the sport while protecting the regular season. We also value the bowl tradition and recognize the many benefits it brings to student-athletes.

"We have more work to do and more discussions to have with our presidents, who are the parties that will make the final decisions about the future structure of college football's post-season."

There are several key issues yet to be decided: whether the playoff field would consist of the top four teams or involve conference champions and how the revenue will be divided among the 11 conferences and Notre Dame.

This will not be easy, sources told CBSSports.com.

"I'm dead serious that we have a long way to go," a BCS source said. "There are significant issues that must be resolved."

For the past month, the group has said that a four-team playoff model would be presented to the oversight committee. And that remains the leading candidate.

However, Pac-12 commissioner Larry Scott said recently the plus-one model, which features the top two ranked teams playing for the national title after the bowl games, was still a possibility.

On Wednesday, Scott was asked if the plus-one model was still on the table, but he said he wouldn't speak specifically about one model.

BCS executive director Bill Hancock said that "everything is still on the table." Although, ACC commissioner John Swofford said the focus remains a four-team playoff.

On April 26, Hancock said the goal was to "get down to two, maybe three [playoff models]. I think we’re making good progress on that. I think we’re going to make it [by June 20]."

After Wednesday's meeting, it appears it's going to come down to the wire.
