Tamina Snuka is in fact out with a concussion. She suffered the injury in a match taped for WWE Superstars against Natalya on June 3, 2013. We first reported the news in Issue #12 of the Powerslam Newsletter.
Concussions are a hot topic in WWE right now with Tamina's concussion being the third in just over a month. Dolph Ziggler went out with a concussion on May 7, Fandango suffered a concussion on June 4. WWE is taking the head injuries very serious, immediately pulling talent when symptoms begin and not clearing them until an ImPACT concussion test is passed along with other tests to assure they are 100% healthy.
