Swindon Town chairman Lee Power will acct as the club's caretaker manager after dismissing manager Mark Cooper.
Power will be in charge for the Robins' game against Oldham Athletic on Tuesday, but won't be the next permanent manager of the club.

The club has yet to make a statement but said on its official Twitter site: "Swindon Town Football Club have (on Saturday) evening parted company with manager, Mark Cooper.
