Government spokesmen in Jordan say a reported attack on King Abdullah was a quarrel with police, not an attempted assault on the monarch.
A security official said earlier Monday that some youths threw stones and empty bottles at the king's motorcade as he visited the southern town of Tafila.
However, a government spokesman denies there was any attack. He says some young Jordanians were trying to greet the king and became riled when police tried to push them away.
The king went to Tafila to inspect several development projects.
On Sunday, King Abdullah said he is pursuing reforms that will allow future governments to be formed based on an elected parliamentary majority. The measure is a key demand of pro-democracy protesters calling for greater political representation.
In a nationally televised address, the king said a royal commission is now exploring "possible amendments" to the constitution.
He did not elaborate on the reforms or give a timetable for implementation, saying sudden change could lead to chaos and unrest.
King Abdullah is considered an important U.S. ally. He vowed a tougher fight against corruption while warning the Jordanian media and political parties against creating a climate of hatred.
Since January, the king has faced protesters demanding a newly elected parliament to replace one widely seen as ineffective and complacent.
