#2 Tamina

Tamina's last main roster televised match was at WrestleMania where she competed alongside Nia Jax in an attempt to win the WWE Women's Tag-Team Titles and she hasn't been on television since so people could be forgiven for not knowing she's injured and not just not on television.
But Tamina had been wrestling on the house show circuit ever since WrestleMania until her match on July 12th at a house show in Maine when she had to be attended to at ringside during a match teaming with Sarah Logan against Dana Brooke and Naomi.
Tamina was physically knocked out during the match after taking a stiff knee from Naomi, although she was able to walk out with assistance.
It has since been revealed that Tamina Snuka picked up a concussion and she's been out of action as a result with no current timetable for a return!
Fightful reported that there was particular concern from WWE about their handling of Tamina's injury because it happened publicly and was attended to at ringside
