Walter Smith knows he will have to keep an eye on Kenny Miller after the striker again suffered from shin splints during Wednesday's friendly in Sydney.
Miller, who felt the recurring problem had settled down after more than two weeks of pain, was forced off after an hour of the goalless draw, which was played in terrible conditions.
However, manager Smith dispelled fears over injuries suffered by Kyle Lafferty and Lee McCulloch, both of whom limped off during the water-logged match.
"Kenny came off with the same problem that has been bothering him and we just have to watch it doesn't become a chronic one," said Smith.
"It's one of those things which is OK during the game but as soon as he stops it causes him a bit of pain.
"Hopefully we can get over the weekend's game because when we travel back he will then have a few days' recovery and he won't have to play against Clyde next midweek.
"Kyle had a little bit of cramp in his calf as you'd expect because he did a lot of running tonight.
"He'll be OK and the same should apply to Lee and he just took a kick."
Despite the conditions limiting quality football, Smith was pleased to see his team work hard as they struggled against the saturated pitch.
"It was difficult for both teams. If we get rain at this time of year back home the pitches normally handle it very well," Smith told Rangers' official website.
"But here the water was starting to lie on top of the pitch and it was awkward for both sides.
"It was still beneficial from the point of view that the boys had to work really hard to get anything going.
"I felt Sydney put us under a bit of pressure in the first half then we did more of that after the break.
"We showed a good level of fitness for this time of the year and that was a pleasing factor, even if it was the only positive for us."
