What happened: Ronald sustained the muscle injury while playing the full 90 minutes as an emergency right-back in last weekend's loss to West Ham United. He had recently worked his way back into head coach Vitor Matos' rotation after a deadline-day move to Millwall fell through, forcing Swansea City to improvise on the back line while Josh Key remained out with a hamstring issue and Filip Lissah served a suspension.

Why it matters: The absence removes an in-form wide option for the Championship leaders just as Ronald had re-established his role off the bench. Matos noted the opening could bring on-loan Manchester City teenager Jeremy Monga into a matchday squad for the first time since his arrival last month, while the Swansea boss also brushed off speculation linking him to Crystal Palace amid pressure on Eagles manager Pierre Sage.

What to watch: Swansea visit Queens Park Rangers on Saturday at 15:00 BST with Lissah expected to reclaim the right-back spot and Monga in contention for squad inclusion.
