Ijaz's maternal uncle, Jahangir Khan, further contributed to the family's cricketing legacy by representing All-India in Test matches during the tours of England in 1932 and 1936.

In the semi-final victory against Punjab, Ijaz contributed with bowling figures of 4–45 in the second innings at Railway Stadium, securing the win based on the first-innings lead.
