Rugby:Leinster have launched an internal investigation after Northampton prop Brian Mujati alleged he was racially abused on the field during Friday's pre-season defeat to the Saints at Donnybrook.

Mujati used his Twitter account to make the accusations after the Saints beat Leinster 19-14 last night.

The Zimbabwean-born South Africa international has since removed the claims.

“Following allegations made by a Northampton Saints player this morning via his personal Twitter account, Leinster Rugby are holding a full internal investigation,” a statement read this afternoon.

“The managements of both teams are in close communication and hopefully the matter will be resolved as soon as possible.

“No further comment will be made at this time until that resolution has been reached.”
