Founded in 1972, the Welsh Rugby Charitable Trust supports severely injured players in Wales.
It invites them to all home games and each year the WRU hosts a "family day" for players and their families.
The highly-anticipated game will kick off at 16:45 GMT on Saturday 15, and will see England attempt to lift their first Six Nations title since 2020.
In contrast, Wales are playing to avoid the Wooden Spoon for finishing bottom after enduring the worst losing sequence in history with 16 successive international defeats.
Prince Williams and Catherine's visit to the capital comes almost three weeks after their visit to Pontypridd, where they learnt how the community is coping following recent devastating flooding.
It marked the couple's first appearance in Wales together since Catherine announced last March she had begun cancer treatment, following the King's own cancer diagnosis.
The princess has made a gradual return to public duties since completing chemotherapy last summer.
