For anyone wondering why Wade Barrett won the IC title back from The Miz after only 24 hours, I just checked the WWE website. The Miz is apparently leaving to film another movie next week. He isn't booked for any event, live show or house show, between now and the beginning of May.
Also, Barrett is supposed to face Bo Dallas for the title on NXT this weekend, and the European tour is coming up.
I'm just going to go ahead and assume their feud will resume around Extreme Rules then.
