WWE Spoilers: Dean Ambrose's SummerSlam Match, Hulk Hogan, Ric Flair, KENTA and More

WWE's SummerSlam pay-per-view airs in less than two weeks on Sunday, Aug. 17 and the match card is not quite filled out yet. But persistent rumors and reports could fill in the picture somewhat.

Firstly, we know Dean Ambrose will face Seth Rollins at the event and that the Lunatic Fringe gets to pick the stipulation for the bout. Ambrose will reveal his choice at tonight's Friday Night Smackdown taping and the expectation is for him to announce a Street Fight. There's no word yet on whether or not he will challenge for Rollins' Money in the Bank briefcase.

Wrestlezone reports WWE is still considering unifying the United States and Intercontinental Championships at SummerSlam, and this would likely occur in a Triple Threat match between Sheamus, The Miz and Dolph Ziggler. WWE has announced Miz vs. Ziggler for the pay-per-view, so any decision to make this a Triple Threat would happen at the 11^th hour.

WWE has announced a special celebration for Hulk Hogan's birthday on next week's episode of Monday Night Raw and has teased some special guests. One of these surprises will reportedly be Ric Flair, though it's unclear how the company plans to use him.

Finally, rumors are circulating that Kenta will make his WWE debut at the NXT Takeover 2 special event on the WWE Network on Sept. 11.
