Following the "attack" on Kane during last night's WWE RAW broadcast, there was a lot of speculation that the angle was leading towards a Wyatt Family vs. Kane and The Undertaker feud/match at the WWE SummerSlam pay-per-view in August.
According to a WWE source, The Undertaker is not healthy right now and may not be ready to return in time for SummerSlam. The source notes that the new injury took place during 'Taker's last TV angle, when The Shield took him out.
We hope to have more soon. Stay tuned!
