ESPN reported the league found no immediate contact was made with Luck or persons of consequence in his inner circle, including his former agent.
The Colts own the contract rights to Luck because he retired in 2019 with three years left on his deal.
Colts owner Jim Irsay created a stir around the potential violation of the NFL anti-tampering policy first in a Twitter post and later by calling league commissioner Roger Goodell.
"If any NFL team attempted to contact Andrew Luck (or any associate of him) ... to play for their Franchise -- it would be a clear violation of the League's Tampering Policy," Irsay posted earlier this month.
