GWS midfielder Jacob Hopper will miss the next four weeks of football after suffering an ankle injury at training.

Hopper was nearing a return after recovering from finger surgery following an injury suffered against the Saints in round seven, but will now be out of action for another month.

The 20-year-old has played six games for the Giants so far in 2017, and GWS' Head of Athletic Performance David Joyce told the club's website it was a disappointing setback.

โ€œThis is an unfortunate setback for Jacob who had done an enormous amount of work in recent weeks," he said.

โ€œHe has demonstrated his resilience in the past and weโ€™re confident he will attack the rehab plan for this injury with his normal dedication and professionalism.

โ€œWe look forward to seeing him back playing an important role for us in the weeks to come.โ€

Giants midfielder Josh Kelly also suffered an injury over the weekend, and will face a fitness test later in the week to determine his availability for their clash with Brisbane on Saturday.

Kelly complained of a hip injury during training over the weekend, and hasn't missed a game so far this season.
