GREEN BAY, Wis. (AP) -- The Green Bay Packers have accepted the resignation of John Jones, the man who was selected to succeed Bob Harlan as president and CEO but said his medical problems prevented him from continuing with the team.

The 70-year-old Harlan had been expected to retire May 30 but stayed on because Jones had abruptly taken a paid leave of absence four days earlier.

In the team's news release today, Jones said the aftereffects of the heart troubles that hit in June 2006 made it difficult for him to stay on the job.

He says he had to undergo a series of complex heart surgeries, and he's grateful to have survived.

But he says he's found the residual effects of the surgeries made it difficult for him to continue in his job.

The Packers executive committee formally accepted his resignation and formed a search committee to select a new chief executive officer.

No financial details of the resignation were released.
