Leicester Tigers say they will "take further action if appropriate" after reports of an incident involving some of their players in a bar in Portugal.
It has been claimed a "violent confrontation" with security staff took place in a pub during the Premiership side's training camp in the Algarve.
"The players made us aware of an incident when they were given a night off," a club spokesman told BBC Sport.
"The club have co-operated fully with the authorities."
The spokesman added: "While we believe this is the end of the matter, we will take further action if appropriate."
