Example Input: BEIRUT (Reuters) - Lebanonâs Shiâite Hezbollah group on Sunday accused Saudi Arabia of forcing  Lebanese Prime Minister Saad al-Hariri  to quit  and called for calm in an effort to contain the political crisis unleashed by  his  resignation.

Sayyed Hassan Nasrallah  the leader of Iran-backed Hezbollah  said there should be no political escalation in response to  Hariri âs declaration on Saturday  which was made from Saudi Arabia and came as surprise even to his aides.
 Hariri   in a televised speech  said there was a plot to kill him  and accused Hezbollah and its Iranian backers of sowing strife in the Arab world.
Nasrallah said âlegitimate questionsâ were being asked over whether  Hariri  had been detained in Saudi Arabia  where news emerged on Sunday that royals  ministers and investors had been arrested in an anti-corruption purge.
Speaking in a televised address  Nasrallah said: âThe resignation was a Saudi decision dictated to  Prime Minister Saad al-Hariri  and was forced on  him .â
Nasrallah said Lebanonâs political leaders expected  Hariri  to return to Lebanon on Thursday âif  he  is allowedâ to travel.
Sunni Muslim Saudi Arabia  a political ally of  Hariri   is locked in a bitter tussle for power across the Middle East with Shiâite Iran and its allies  including Hezbollah.
Lebanese President Michel Aoun will not accept  Hariri âs resignation until  he  returns to Lebanon to explain his reasons  palace sources said on Sunday  delaying for now the politically difficult consultations over his successor.
Nasrallah said he would not comment on accusations leveled against Hezbollah by  Hariri   describing his resignation announcement as a Saudi statement.
 Hariri âs resignation toppled a coalition government that included Hezbollah  thrusting Lebanon back into the frontline of the Saudi-Iranian regional rivalry and risking an open-ended political crisis.
Nasrallah said he had thought things were going well and had not wanted  Hariri  to quit.
 Hariri  allies in Lebanon have denied suggestions he had been detained and a photograph was published on his Twitter account showing him with Saudi Arabiaâs newly appointed ambassador to Lebanon  Walid al-Yaaqoub.
News of high-level arrests in Saudi Arabia fueled social media speculation in Lebanon that Hariri  a Saudi national  was a target. Nasrallah said âthere was legitimate concernâ  asking if  Hariri  had anything to do âwith this internal struggle between the princesâ.
Saudi-owned newspaper Asharq al-Awsat cited unnamed sources close to  Hariri  as speculating that  he  would probably remain outside Lebanon because of the security threat against  him .
In Lebanonâs sectarian system the president must be a Maronite Catholic  the prime minister a Sunni and the speaker of parliament a Shiâite.  Hariri  is Lebanonâs most influential Sunni politician.

Example Input: It has been a long time since two teams induced as many sofa spasms as the New England Patriots and Pittsburgh Steelers did  with those three false endings in the last two minutes. You thought  finally  the NFL is all about the game again. But just then  the skin-crawly headline came across the bottom of the screen  turning attention away from Tom Brady and Ben Roethlisberger to an old pot-belly named Jerry Richardson.
[Panthers owner Jerry Richardson announces plan to sell team amid NFL investigation]
Yet the viewer’s head swiveled back and forth between the Patriots-Steelers epic in the icing rain  and the alleged fetishes and racial attitudes of Carolina Panthers owner  Richardson  in  his  owner suite. On Friday  the Panthers announced that Richardson was being investigated for workplace abuses  and by Sunday morning  the story had exploded when Sports Illustrated published a host of sordid specific accusations ranging from sexual harassment to using a racial slur against an employee. These included Richardson supposedly asking to shave the legs of female employees and demanding to examine their backsides in their jeans.
But that wasn’t the end of the NFL day. Not thirty minutes after the final play in Pittsburgh  with fans still filing out of the stadium  came the seismic announcement that  Richardson  will be selling the Panthers  the franchise  he  has owned since it was founded in 1993. No explanation was offered  or needed. You have to assume that the disclosures were going to get uglier.
[Analysis: Forget the catch rule. The league has a replay problem] 
Richardson  is a perfect example of the extent to which the sheer girths of owners’ egos are eclipsing what should be the NFL’s true narrative: the game. Their incessant internecine rivalries and power struggles have become a chronic story line. It was  Richardson  who set the poisonous current tone of management-player relations  when  he  declared during the 2011 collective bargaining that the owners had “a [expletive] deal and we’re going to take back our league and [expletive] do something about it.” It was  Richardson  who  inexplicably grown arrogant on  his  Hardees franchise money  sat across a table and barked at Peyton Manning: “Do I need to help you read a revenue chart  son? Because I don’t know if you know how to read that.”
Richardson  no doubt  is also capable of individual kindness  and other owners will profess sorrow over his decision to sell  and wax nostalgic over the fact that he once caught passes from Johnny Unitas with the 1959-60 Baltimore Colts.  Richardson  is a self-made man  the first player since George Halas to acquire an ownership stake. But  Richardson   sadly  has acted as a toxic hardliner devoted to ensuring that no other player would ever be treated like a partner or equal.
