IRVING, Texas – As expected, the NFL's salary cap is poised for another significant spike.

Club executives attending the league's annual labor seminar on Tuesday were told that the cap for 2015 is projected to rise to $138 million to $141 million, two club executives at the meeting told USA TODAY Sports. The executives did not want their identities revealed because they are not authorized to announce the information.

That's a rise of at least $5 million from the current $133 million cap.

The labor seminar was held in advance of the one-day NFL owners meeting on Wednesday, when the agenda is to be dominated by efforts to revise the NFL's personal conduct policy.

The projection provided Tuesday is an NFL version of an annual crop report, and is essentially a planning guideline for clubs. The final cap number, tied to the players' share of revenues, will be settled on before the start of the new NFL year and opening of the free agent market in March after a full accounting of league revenues.
