Finn Balor suffered a concussion on last night's "Superstar Shakeup" edition of WWE RAW from Long Island, according to PWInsider.
The injury came when he took the stiff forearm shot from Jinder Mahal during their match, as seen below. Fans have been tweeting negative comments to Mahal since the match happened last night. It was Balor's first singles match on WWE television, although he worked singles matches against Mahal at live events last month.
No word yet on how long Balor might be out but we will keep you updated.

Hopefully this isn't true, but the way he got hit and then fell to the mat, it looked like he got knocked out legitimately.
Hopefully he won't be out for long and all is well with Finn.
