What's the story?At last night's NXT live event in Omaha, Tyler Breeze made his return to the yellow brand to take on Velveteen Dream, but the real news came from the man in the black and white shirt calling the match.WWE referee Tom Castor suffered a broken leg during the main event, yet continued to call the match until its conclusion before being taken to hospital.WARNING: Graphic photos from the incident belowIn case you didn't know...Tom Castor is one of NXT's prominent referees and, while the men and women calling the action rarely get a spotlight, they're the people who make a match tick and keep the wheels turning.California-born Castor often referees main events and has called several high profile NXT matches, despite only being with the company since 2017, and has also featured on SmackDown Live and 205 Live.My power level is immeasurable...and today, I bring it to Columbus, OH on this #NXTRoadtrip!#BaskInMyGlory #iAmLimitless pic.twitter.com/XF0IfI9kXy— Beast Lee (@RealKeithLee) February 28, 2019The heart of the matterThere were a lot of eyes on last night's NXT live event in Omaha, not least because the main event would see Tyler Breeze, who has most recently been plying his trade on the main roster, make his return to the yellow brand to take on NXT North American Champion Velveteen Dream.The real news, though, didn't come from the former Fashion Police star or one of NXT's hottest prospects - but the man officiating the match.WWE referee Tom Castor suffered a broken leg during the main event, yet continued to call the match until its conclusion before being taken to hospital.The injury occurred when the referee took a superkick and his leg snapped under his own weight.WARNING: Graphic photos and videos from the incident belowScary news out of #NXT live event.At tonight's #NXTlive event in #Omaha, referee #TomCastor suffered a broken leg during the main event between #VelveteenDream and #TylerBreeze.
