While a settlement was reached in the case earlier this week, the NFL said Manning will not be punished under the league's personal conduct policy.
"We monitored the situation and are satisfied that it is a civil matter that was resolved," NFL spokesman Brian McCarthy wrote in an email to profootballtalks.com. "Not a (Personal Conduct Policy) issue."
Three sports memorabilia collectors who accused Manning of providing fraudulent "game-worn" equipment that was sold to fans announced a settlement to their lawsuit on Monday.
The three collectors -- Eric Inselberg, Michael Jakab and Sean Godown -- had sought triple the amount of their alleged losses (which totaled less than $20,000) for purchasing two helmets that were billed as worn by Manning.
They also had sought punitive damages in the lawsuit that alleged Manning delivered the memorabilia to Steiner Sports with a signed letter claiming that they were "game used."
At the center of the dispute were messages from Manning to a team equipment manager asking for helmets "that can pass as game used."
Manning, a two-time Super Bowl-winning quarterback, and the Giants had denied the allegations and characterized the suit as "inflammatory and baseless" in court filings.
