The widow of Danny Jones will perform the traditional hymn of 'Abide With Me' prior to the Challenge Cup Final between Hull KR and Leeds.
Lizzie Jones - a professional singer - lost husband Danny after he collapsed while playing for Keighley in May, dying from an undiagnosed hereditary heart disease.
Danny's death prompted screening for all Rugby League players, to prevent a similar tragedy happening in the future:
Wales international Jones was survived by Lizzie and twin daughters, with a trust set-up by fans and contributed to by all corners of the sport to secure their futures currently standing at over £230,000.
Lizzie's performance at Wembley on August 29 will see her step on the same field her husband played on for his country against New Zealand in 2011.
