LISBON (Reuters) - Portugal have called up center back Sereno to replace the injured Bruno Alves for the World Cup Group F qualifying matches against Israel on Friday and Luxembourg four days later.
Sereno plays for Turkish top-flight club Kayserispor and won his first international cap in June.
The Portuguese Football Federation confirmed the withdrawal of experienced Fenerbahce defender Alves in a statement but did not disclose his injury.
Portugal are second in the table, one point behind leaders Russia and five ahead of Israel. Luxembourg are second from bottom.
