5 WWE Main Roster stars who might be worried about NXT stars appearing on their shows, and 5 who have nothing to worry about

Might be worried about NXT Call ups #4: Heavy Machinery

Otis and Tucker, Heavy Machinery

When it comes to pro wrestling credentials, it's hard to be Heavy Machinery. Both Tucker Knight and Otis Dozovic were highly decorated amateur wrestling champions. Both are well over three hundred pounds and have the strength to match.

They were one of NXT's most popular acts in spite of never capturing the NXT tag team titles, and when they came to the main roster big things were expected of them. However, they seem to be appearing on television less and less, and recently they had their names shortened to just Tucker and Otis, which is a sign that the WWE is trying to simplify their characters so they will be more easily remembered by fans.

Heavy Machinery might need to be worried about the slew of NXT call ups taking their spot on the main roster.
