TNA posted on ImpactWrestling.com that Gail Kim suffered a separated shoulder at the hands of new Knockouts Champion Havok. They list Kim as "out indefinitely." You can read the article at this link.
This appears to be storyline-only as Gail is featured in matches that were taped for November episodes of Impact Wrestling. Things were taped out of order so it's hard to say when they will air, other than they are coming.
