Wembley stewards investigated claims of a row between Wolves fans and members of Troy Deeney's family in an executive box.
There were reports of coffee being thrown and gestures made from the executive box and security staff took statements after the row which flared up during the dramatic FA Cup semi final.
Watford captain Deeney scored the injury time penalty to take the tie into extra time before Watford eventually came back from 2-0 down to win 3-2 and reach the final.
It is understood that Wembley security and the Football Association are taking no further action.
Meanwhile, Deeney branded Wolves' Raul Jimenez a "loser" and mocked his mask celebration after their dramatic match.

Deeney said he would have 'lost his head' if he had noticed the Wolves star pulling on a wrestling-style mask to celebrate his 62nd-minute goal which put his side 2-0 up.
After watching a replay of the celebration on beIN Sports, Deeney said: "I'm glad he put that mask on - he could wear it out now as well, now he's a loser. So, enjoy the mask - we got the victory."
Deeney's injury-time penalty dragged Watford level before Gerard Deulofeu's goal in extra-time, his second of the game, completed his side's stunning 3-2 comeback win.
Deeney stressed he is a big fan of Jimenez, who signed a permanent deal with Wolves earlier this week, but argued the Mexican star's celebrations were premature.
"He's a top, top player," added Deeney. "It was a great finish, but I didn't see the mask thing. I'm quite happy I only saw it now because I probably would have lost my head if I saw that.
"I think you've got to wear the mask and do all that stuff when you know you're going to win the game."
