A youthful Rhinos side, missing several influential players and with others out of position, were sunk in a 15-minute spell during the first half when Catalans scored four successive tries.
Rhinos failed to cope with the power of Dragons’ pack, particularly Sam Kasiano, but showed good spirit in a second half fightback.
Here’s how the players rated.
