Drew Rosenhaus -- Divorce Case Dismissed ... Staying Married to Hot Wife

Sports mega-agent Drew Rosenhaus has opted not to test free agency ... and instead he's officially calling off the divorce and staying married to his insanely hot wife ... TMZ Sports has learned.

As we previously reported, Rosenhaus filed for divorce from Lisa Thomson back in January following an epic blowout at their home in Miami, in which the cops were called to calm things down.

But sources close to the couple say ... both sides wanted to reconcile -- and they did. As one person connected to the situation says, "There was a rough patch. They worked through it and their future is bright."

As for the divorce, the case was officially dismissed because Drew never took the proper steps to move the case forward.

As for Lisa, she recently posted a photo of the two together with the caption, "Date night with my handsome husband."
