Wolverhampton Wanderers midfielder Karl Henry has heavily criticised the standard of officiating over the weekend.

The likes of West Ham United's Carlton Cole and Darron Gibson of Everton were both handed red cards that have been viewed by many pundits and media outlets as harsh.

Discussing those incidents and others on the social networking site Twitter, Henry has accused a number of referees of having "zero understanding of the game of football".

"Some of the red cards i've seen this weekend are an absolute joke!! Some referees have zero understanding of the game of football," he said. "Important matches are runied when underqualified refs make game changing WRONG decisions. What is the criteria to become a top level ref?

"To make it worse, some tv pundits sit on the fence and say things like, ' That was harsh' or 'It's a controversial one.'

"You're on tv to give football fans your expert views. Bad refs need to be exposed and pundits that sit on the fence should be fired!!!"

Henry has been sent off once this season.
