It is feared Morris, who suffered a hamstring tear in the final play of the heated clash against South Sydney at ANZ Stadium last Friday, will miss at least a month and potentially be unable to return before Blues coach Laurie Daley announces his team for game one on May 19.

His brother Josh is one of four players facing possible charges when the match review committee meets on Monday morning, with James Graham, David Klemmer and Sam Kasiano also facing suspension.

In-form centre Tim Lafai, who left ANZ Stadium with his leg in a knee brace, faces up to two months on the sidelines as a result of the injury he picked up against the Rabbitohs.

The Canterbury skipper is likely to attract two charges from the final minutes of play. Graham is expected to be hit with a dangerous contact charge for his charge-down attempt on Adam Reynolds that left the Rabbitohs play-maker with a knee injury.

It is understood the fact Reynolds was injured and faces a lengthy period on the sidelines with a torn lateral ligament will be a factor in determining Graham's sentence, almost guaranteeing he will miss this Sunday's clash with the high-flying St George Illawarra at ANZ Stadium.

His verbal abuse of the referees in the exchanges that followed the penalty being awarded to South Sydney is likely to be deemed as contrary conduct.

Klemmer also faces a contrary conduct charge after he unleashed a tirade on referee Gerard Sutton, heard saying "you're f---ed, you're off your face" before he was sent to the sin bin on the stroke of full-time.

It won't be the first time a player has been suspended for swearing at a match official.

Newcastle legend Andrew Johns, who on the Sunday Footy Show admitted regret over the way he treated referees during his career, copped a two-match ban for verbally abusing touch judge Matt Cecchin in a game for the Knights in 2006.

Cowboys skipper Johnathan Thurston was charged with detrimental conduct in 2010 after he abused referee Jason Robinson, however Thurston was successful in getting off at the judiciary on a technicality around the interpretation of detrimental.

Thurston has since cleaned up his act and prides himself on controlling his emotions on the paddock after several run-ins with the match officials during the first half of his career.

Josh Morris was also placed on report for making contact with the head of Issac Luke with his boot as the Rabbitohs hooker was attempting to score a try in the first half.

The video referee later awarded the Rabbitohs an eight-point try, with Morris placed on report for using his foot trying to stop the try. He will either be charged with dangerous contact (head) or kicking. A grade-one dangerous contact charge will see the Origin centre miss one match, while a grade-one kicking charge will see him miss two games.

Kasiano may also find himself in hot water for the same tackle, despite not being placed on report. The Canterbury prop led with his knees as he charged towards Luke in a bid to prevent the try, making contact with the head of the Rabbitohs' rake.

It's understood the match review committee has identified the collision and will examine it in the meeting on Monday morning.

The injuries and potential suspensions could force coach Des Hasler to make wholesale changes to his side, with a third of the team he named last Friday possibly unavailable for the clash against the Dragons.

Sam Perrett is likely to shift back to fullback to cover for the injured Brett Morris, while grand final winger Corey Thompson is expected to slot back on to the wing to fill the void left by Perrett's transition.

Moses Mbye, who filled in at five-eighth while Josh Reynolds was injured, is likely to shift into the centres with Reynolds making a successful return from injury against the Rabbitohs.

If Graham is suspended, halfback Trent Hodkinson is the logical option to lead the Bulldogs as skipper.
