Bodo/Glimt head coach Kjetil Knutsen and Roma goalkeeping coach Nuno Santos have been provisionally suspended by UEFA following assault allegations.

Santos was accused of assaulting Knutsen in the tunnel after Jose Mourinho's men fell to a 2-1 first-leg defeat in their Europa League Conference quarter-final in Norway last Thursday. 

Both clubs released statements in the aftermath of the incident, with Roma announcing that they were cooperating with UEFA and local authorities to investigate the claims.

The Norwegian champions accused their opponents of "bombarding the media with untruths" relating to the altercation, and European football's governing body has since announced its decision on the matter.

Both coaches will be provisionally suspended from European fixtures until a further ruling is made on the case by UEFA's Control, Ethics and Disciplinary Body.

Knutsen alleged that Santos grabbed him by the neck and pushed him against a wall during a heated alteration outside the dressing rooms after the match.

The encounter marked the second time the Norwegian side have beaten Roma in this season's competition, with a first-half Lorenzo Pellegrini goal cancelled out by second-half strikes from Ulrik Saltnes and Hugo Vetlesen. 

Roma will attempt to overturn the first-leg deficit when they welcome Bodo/Glimt to the Stadio Olimpico for the crucial return leg on Thursday.
