Celtic stars Shane Duffy and Mikey Johnston's agency Base Soccer has followed Rangers and Swansea's lead by urging their player and management clients to take part in a week-long social media boycott.

We told how Gers stars had opted to stay off all social media platforms in a bid to combat online abuse suffered. It comes in the wake of Glen Kamara and Kemar Roofe to name just two players who were subjected to racial discrimination and branded "n****" following the club's Europa League match with Slavia Prague.

Kamara continues to fight after he was allegedly branded a "f***ing monkey" by Czech defender Ondrej Kudela.

Glasgow Times:

Base, who represent the likes of Duffy and Johnston, as well as Hibs' Ofir Marciano, Andy Considine at Aberdeen and Josh McPake at the Light Blues, have taken a stand against abuse.

From 5pm on Friday evening the agency urged all clients and staff to stay off social media for seven days. And they told how they would not be posting from their own official channels.

A statement read: "CAA Base has chosen to follow the lead of clubs and take a stance in the battle against abuse and discrimination on social media. From 5pm today we will not post any content on our social media for 7 days and have invited our staff and clients to do the same."

Base also look after Tottenham's Heung-Min Son, Raphaele Varane of Real Madrid and James Maddison at Leicester City, among hundreds of others.

We told recently how Celtic's defender Duffy was the victim of horrific sectarian abuse earlier this season on Instagram. The vile troll who sent sickening messages called the Irishman a '"fenian ugly b******", adding "you're f***ng s*** you c***'.

The idiot also aimed a final insult: "Haha ur dads dead" after Duffy's father passed away last year.

Rangers confirmed they would boycott social media for one week. Managing director Stewart Robertson said: "We can confirm that as a board and as a club, we are fully behind our players and management team on this issue. Furthermore we have arranged to meet Facebook and Instagram to underline our growing concerns.

"Having spoken to a wide range of clubs across the UK, we know these concerns are shared by all clubs and it is fair to say everyone is losing patience with the lack of action from social media companies. Rangers hope is that clear and direct action is taken from social media platforms. The basic verification of users, as part of the sign-up process, to any social media platform, will ensure that users are both identifiable and accountable for their actions and words.

"We will raise this next week in our scheduled meetings. Rangers has driven its flagship Everyone Anyone campaign forward rigorously, drawing praise and support from fellow clubs, governing bodies and politicians, and we will continue to stand firmly against all forms of discrimination. Enough is enough."
