According to Dave Meltzer, Luke Harper and Erick Rowan have been split up in the WWE Draft. The latter was moved to RAW on Monday but there was no mention of Harper, someone we know is anxious to actually leave the company the second his contract expires.
Harper was sitting his contract out at home before WWE called him back for Clash of Champions. He them teamed with Rowan as part of that disastrous Roman Reigns storyline.
He hasn't been seen since Reigns and Daniel Bryan defeated him and Rowan at Hell in a Cell and it's probably safe to now assume that his attitude about leaving WWE has not changed so he's returned home to continue to wait out that contract.
With Rowan on RAW and Bryan and Reigns on SmackDown, it's clear that WWE is looking to move on from this disastrous feud (which contributed to Eric Bischoff's firing) as quickly as possible.
