10:02 AM PT -- A spokesperson for the Arlington Police Department tells TMZ Sports ... no arrests were made, explaining, "it does not appear either of the men involved or the vendor whose items were knocked over contacted us to file a report with us."

Two fans at the Cowboys vs. Eagles game got into a wild brawl ... and things turned so violent during the fight, the combatants almost destroyed thousands of dollars worth of memorabilia.

The scrap went down during the Cowboys' win over Philadelphia ... when a man wearing a Raiders Michael Crabtree jersey got into it with a Dallas fan.

It's unclear what started it all ... but video from the scene shows the two were throwing some serious haymakers at each other -- before they spilled into a pop-up shop full of rare, signed jerseys, photos and more.

Thankfully, while the two were going at it, none of the items appeared to be damaged.

The guys, however, continued to slug each other even after they moved on from the memorabilia tent ... punching each other in the face over and over again.

No word on if any arrests were made -- the footage of the tilt cut out before the fight concluded -- but it seems bystanders ultimately stepped in to calm things down.

As for the action on the field at AT&T Stadium -- there wasn't much of a fight there ... the Cowboys won by 20 in a game that never really felt close.
