"The Lunatic Fringe" Dean Ambrose returned from injury tonight after being on-the-shelf for almost 8 months ... and he was FIRED UP! 

Ambrose re-emerged with a new look during the final segment of Monday Night Raw after Seth Rollins let it be known Dean would be in his corner when he faces Dolph Ziggler at SummerSlam.

The two wrestlers then made their way to the ring and brawled with Dolph and Drew McIntyre.

As we previously reported, Dean underwent surgery in December '17 to repair a torn triceps tendon.

Watch the video of his return below.
