Does anyone know when umaga will be back?

Umaga was brought to the television tapings this past week, but wasn't used. Upon his return to WWE, Umaga will remain on the SmackDown brand and is expected to be involved in Undertaker's next program. Umaga has been out of action since suffering a torn PCL at a SmackDown live event in Johnson City, TN on August 2, 2008 during a match with Jeff Hardy.
