Delph, 19, whose home address is in Bradford, was almost twice the legal limit when police pulled him over two days before Christmas.
The England U-21 international was breathalysed and the test revealed he had 66 micrograms of alcohol in 100 millilitres of breath.
The legal limit is 35 micrograms. Having admitted a charge of drink driving, Delph was also ordered to pay £60 costs and a victim surcharge of £15.
