The NFL has finished with their investigations on the alleged use of the illegal sticky substance in the Monday Night game against the Denver Broncos on Oct. 15.
However they were fined $20,000 for not providing the towels when asked and failing to cooperate with NFL officials.
Statement from the NFL on the investigation.
"Following a review of the San Diego Chargers use of towels that included an adhesive substance in an October 15 game against the Denver Broncos, the NFL has determined that the club did not violate a competitive rule by use of the towels.
However, NFL game officials are charged with protecting the integrity and competitive fairness of the games and club staff members, like players and coaches, have a clear obligation to cooperate in this effort and comply with the direction of game officials. As a result of the failure of club staff to follow the directive of a game official to immediately surrender the towels when directed to do so, and to attempt to conceal the towels, the Chargers have been fined $20,000."'
