Marshall joins Port Vale
Port Vale have announced the signing of winger Mark Marshall from League One rivals Coventry.
Marshall has signed a one-year deal at Vale after making 14 appearances for Coventry since joining in February. He has also had spells at Barnet, Hereford and Swindon.
The 27-year-old was once banned from football for two years after he failed a drug test for a banned stimulant.
