The 31-year-old has been sidelined by a hamstring injury but came off the bench in Saturday's 0-0 draw with Newcastle.
"We've had to tread carefully with Grant over the past couple of weeks," Hughton told BBC Radio Norfolk.
"What's far more important is that we have Grant available for next week, the week after and the week after."
"There was a fear that if we started him then we would be putting him a little bit at risk," added Hughton.
"So we have to make these tough decisions. Most would have liked to have seen us start with Grant.
"We hope now he has a good week's training and will be available from next week onwards."
