The National Hockey League Players' Association may have more turmoil at the top.

In a story first reported by cable sports network TSN, NHLPA executive director Paul Kelly may have his job challenged when the union's 30-member executive committee convenes Sunday and Monday in Chicago.

Kelly has held the position for less than two years.

Citing unnamed sources, the report says NHLPA interim ombudsman Buzz Hargrove is expected to make a presentation to the committee identifying concerns within the association about Kelly's leadership.

No details have emerged about the nature of the concerns.

The sources said it's possible the executive committee could vote to have Kelly removed without consent from the full membership of NHL players.

Kelly succeeded Ted Saskin as executive director in 2007 after Saskin was let go amid allegations he had been monitoring players' confidential emails.
