He tried to carry on but eventually had to come off in the second half, and Bond admits that losing Austin would be a big blow to QPR's promotion hopes.
"Charlie's got a problem with his shoulder and we don't yet know the extent of it," Bond told Sky Sports News.
"He had to come off after going on as long as he could. In the end it was too much for him and we'll have to assess it.
"He's as game as they come and got his goal from a great cross by Matt Phillips. We know we're reliant on Charlie and didn't need reminding."
Austin has 14 league goals this season.
