Physiotherapist Brien Seeney, more commonly known by his Twitter handle NRL Physio, said same-day travel and the NRL's six-week lockdown were both factors in the masses of injuries being suffered across professional sport.

He described the carnage as the perfect storm, which has the Raiders currently without six players due to injury - although that's been as high as eight.

As revealed by The Canberra Times, the Green Machine are hopeful hooker Siliva Havili (triceps) won't be added to the list as he looks likely to play the Brisbane Broncos at Canberra Stadium on Saturday.

His loss would further compound the absence of Hodgson, leaving the Raiders with just one recognised hooker, Tom Starling, in their squad - although they have just brought Kurt Baptiste into their Apollo bubble on a training contract.

Seeney's analysis has shown overall injuries were down so far this year compared with last, but serious injuries had almost doubled.

That's been an area that's particularly affected the Green Machine, with Hodgson, Sia Soliola (face), Bailey Simonsson (shoulder) and Corey Horsburgh (foot) all likely to miss the rest of the campaign, while Emre Guler (ankle) was expected to spend three months on the sideline.

Seeney revealed Hodgson's injury could have been caused by the time spent in isolated training.

When the NRL season was first suspended back in March players were forced to train alone for six weeks before having just four weeks to prepare for the season restart.

Plus, without the NSW Cup, it also increased the injury risk for anyone coming in to cover injuries as well.

Seeney said all the factors surrounding this season meant there was greater risk for injuries like Hodgson's.

"That's your big contributor. Going from isolation training to present to the club and within three weeks play a game, that's you big contributor," he said.

"Increasing a load that much that quickly increases the injury risk quite significantly.

"Hodgson's knee ... those kind of non-contact injuries are the ones that all of these factors do increase the likelihood of."

As revealed by The Canberra Times, the Raiders have had the hardest travel schedule due to the coronavirus-induced changes to the draw.

That was highlighted on the weekend when they played the Panthers - who have only left Sydney once this season - while the Green Machine have had near-weekly six-hour round trips on game day.

Seeney said that sort of travel led to fatigue and also affected players' ability to recover post game.

Not only could it cause soft-tissue injuries like Michael Oldfield (hamstring), but they would also increase the recovery times by a week or two for all injuries suffered away from home - like Horsburgh, who hurt his foot at Parramatta Stadium.

"Same-day travel and unideal travel circumstances can affect recovery and preparation, and both of those are important for not only performance, but injury risk as well," Seeney said.

"The whole COVID situation has a lot of factors that are contributing to increased risk and the travel just plays a part in that."
