#3. Jeff Hardy

Jeff Hardy has recently become another superstar to be pushed onto the sidelines given his recent knee injuries. Back in April, Hardy became a SmackDown Tag Team Champion alongside his brother Matt, but after the match, Hardy was attacked by Lars Sullivan which was a way to write him off WWE TV because of his knee injury.
The Hardyz were forced to relinquish the SmackDown Tag Team Championships following the attack at the end of April and WWE then released a report that stated that Hardy would be out of action for up to nine months.

According to Sean Ross Sapp of Fightful, Hardy is another WWE superstar whose return date is being listed as November 2nd, which means that the former World Champion would have been on the sidelines for seven months before he makes his return.
