This Sunday, April 15, TNA brings back its all cage-classic pay-per-view: Lockdown.
Lockdown is one of TNA's biggest events of the year (Slammiversary and Bound for Glory make up the rest of TNA's "Big Three").
Since its inception in 2005, there have been some great matches that took place at Lockdown. Lockdown is labeled as TNA's most dangerous pay-per-view of the year. And rightfully so.
