St. George Illawarra will be without Tariq Sims or Jackson Ford for the foreseeable future following the Dragonsโ€™ eight-point loss to the Sydney Roosters.

The Fijian second-rower Sims suffered a shoulder injury during the second half of the Dragonsโ€™ defeat and will have scans in the coming days to determine the severity of the injury.

โ€œHow bad? Iโ€™m not sureโ€ฆ Taz doesnโ€™t really come off, so itโ€™s probably a bit more serious than an average one.โ€ Head coach Paul McGregor said Thursday night in his press conference.

A grade-two AC Joint injury means that Sims could potentially miss a month for the Dragons.

Ford has been cited by the NRL match review committee with a grade three tripping charge on Sydneyโ€™s Luke Keary late in the game.

An early guilty plea will mean that he will miss the Dragonsโ€™ next two games against Parramatta and Brisbane.

"I did see it, the leg went out, no one was hurt, he didn't hit him... I am not sure what will happen from there." McGregor said.
