Mooy helped set up two of Huddersfield's goals but was later taken from the field on a stretcher, amid concerns he had suffered a serious knee injury.
Although Terriers manager David Wagner later confirmed Mooy had suffered no ligament damage, the former Melbourne City star later showed off the stitches he had needed to fix up a nasty-looking cut.
Huddersfield currently sit just outside the Premier League relegation places in 17th place, and next travel to take on bottom side West Bromwich Albion on Saturday February 24 (Sunday February 25 AEDT).
