Regarding why WWE Intercontinental Champion Daniel Bryan was sent home from the recent WWE European tour, a WWE source stated to PWInsider that Bryan is indeed injured.

Bryan reportedly suffered an injury on April 9th at a WWE live event in Dublin, Ireland as he teamed with Dolph Ziggler and Erick Rowan to defeat Sheamus, Bray Wyatt and Bad News Barrett. We're not exactly sure what happened to him but there was an injury in that match that got him sent home.

When Bryan was first sent home, WWE officials expected him to be out of the ring for about a month. No word yet if that time-frame has changed but there's a chance they change Sunday's Extreme Rules match against Barrett.
