Rangers are investigating allegations that Magilton head-butted Hungarian midfielder Akos Buszaky during the 3-1 defeat, an incident which also involved several other Rangers players.

A club statement said: "The club can confirm that manager Jim Magilton has been suspended with immediate effect, pending an internal investigation.

"The suspension relates to an incident which occurred at Monday's Championship fixture against Watford at Vicarage Road.

"The club will be making no further comment at this stage."

Magilton is the second manager this week to be embroiled in a high-profile clash with a player, following Stoke manager Tony Pulis' alleged head butt on James Beattie after the defeat to Arsenal at the weekend.
