 McKinnon was a regular from then on, until official competition was suspended, a period with injury between March and November 1914 excepted.Unfortunately for him, his career with Woolwich Arsenal coincided with their relegation from the First Division in 1913; nevertheless he continued to serve Arsenal (as they had been renamed following their move to Highbury in 1913) as they pushed for promotion.On the issue of the name the volume "Woolwich Arsenal the club that changed football" traces the changes of the club's name and reports that for the 1914/15 season the club defined itself in the programmes and elsewhere as "The Arsenal" (not Arsenal) for the first time on 10 April 1914 but that name was not registered and that formally with the Board of Trade or the Joint Stock Companies, as would have been required to make the change official.
