Brighton & Hove Albion manager Gus Poyet has challenged goalkeepers Michael Poke and Mitch Walker to deputise while number one Peter Brezovan is out injured.
The Slovakian stopper has sustained a fracture to his wrist and he will miss the League One opener against his former club Swindon Town on August 7.
Speaking to the club's official website, Poyet said: "Peter has a wrist injury which could see him sidelined for a month, so Michael and Mitch have the next few games to stake their claim to begin the season at Swindon.
"Understandably Peter began pre-season as first choice after his excellent end to last season, and due to his experience.
"However, he won't be fit, and that presents a chance for one of the other two goalkeepers to seize the shirt for themselves, and prove they are ready to play regular football in League One.
"That opportunity has perhaps come sooner than any of us anticipated, but it's now up to Michael and Mitch to take their chance and show me they are ready to begin the season."
