Various media reports started Weis might leave the Chiefs for Florida after this season.
Haley said Friday he was "unaware of anything."
"It would be news to me," Haley said.
Weis became offensive coordinator in Kansas City this season after getting fired as coach at Notre Dame last year.
He's helped the Chiefs make a worst-to-first turnaround and win the AFC West. Under his tutelage, quarterback Matt Cassel has thrown 27 touchdown passes and only five interceptions.
Weis was not available to reporters.
