[5] Iddon made his first-class debut in May 1924 and gained an established place in the Lancashire team as the 1924 season progressed.
He was part of an under-strength and much-criticised party of fourteen players that Marylebone Cricket Club (MCC) sent to the West Indies for the 1934–35 Test series.
The team was captained by Bob Wyatt and included established Test players in Wally Hammond, Patsy Hendren, Les Ames and Maurice Leyland, but the bowling was weak.
[8] Iddon was himself a good spin bowler but he was selected in all four Tests as a specialist batsman and bowled only eleven overs in the entire series.
[9] Wyatt won the toss but, realising that the pitch had been affected by rain, put West Indies in to bat.
Seeing how bad the pitch was for batting, Wyatt boldly declared the innings closed even though England were still 21 behind, Iddon not out 14.
Play on the third day was delayed till 15:30 and West Indies struggled to 51/6 at tea whereupon their captain Jackie Grant emulated Wyatt by a bold declaration, setting England a target of 73 in conditions that were, according to Wisden, "making the ball rise in disconcerting fashion".
He continued this work through and after the war, but hoped to play cricket as an amateur when normal fixtures recommenced in the 1946 season.
[3][2] Shortly before the season began, Iddon was killed in a motor accident at Madeley, Staffordshire, on 17 April 1946.
[11] In his profile of Iddon, Dave Livermore wrote that his all-round skill made him "an important part of a successful Lancashire team".
This was especially the case when he took his career-best 9/42 in the second innings of the 1937 Roses match, which ended with Lancashire's first win over Yorkshire in five years.
