Mark Williams has not backed down in a row with Darren Morgan who has accused the two-time world champion of being a cyber bully.Former Crucible semi-finalist Morgan, now 51 and playing as an amateur, faced criticism from fellow Welshman Williams over his right to be involved in this week’s Welsh Open.Morgan secured a wild card by winning an amateur event in January, the Robert Harhhy Memorial, beating 16-year-old Jackson Page in the final.Williams claimed that Page, who was later handed a place in the Welsh Open draw due to Joe Swail’s withdrawal, should have been entitled to a wild card in the first instance.The 42-year-old Williams said on Twitter on February 13, regarding Morgan and fellow Welsh wild card Rhydian Richards: “Both of you should count yourselves (lucky) your in it at all.”That and other social media interaction from Williams drew a forceful response this week from Morgan, who told BBC Sport Wales: “I know he’s fighting Jackson’s corner but he’s a total joke.”

Morgan, who lost to Richards in their pre-qualifier at the tournament venue on Monday, said of Williams: “He thinks it’s a bit of banter but there’s consequences to everything people do and say… but where he thinks it’s banter, to a lot of people it’s cyber bullying… he is abusing his position.

“He’s a bully. He’s a keyboard warrior… but he gets away with it.”

Williams reacted by writing on Twitter: “I’m a grown man and can take it on the chin or chinssssss. Jealousy is a horrible thing”

Asked by a user of the social network who Morgan was, Williams said: “I think he was tha fella who used to impersonate a snooker player about 30 years ago”

Morgan’s World Championship semi-final appearance came in 1994, when he lost to Jimmy White in the last four.

Press Association Sport understands no disciplinary action has been taken at this stage over the claims from Morgan.

Teenager Page won his first-round match on Monday at the Welsh Open, beating Sean O’Sullivan 4-3 to set up a last-64 clash with defending champion Stuart Bingham.
