Towering centre half who joined Reading from Swindon Town in January 2011. His experience belied his tender age; by the time Sean turned 20 he had already chalked up fifty first team appearances.
Has a knack of finding the net from set pieces and scored on five occasions for Swindon before electing to join the Royals.
Morrison scored his first Reading goal on his debut in a Carling Cup clash with Charlton Athletic in August 2011, before spending the rest of the campaign on loan at Huddersfield, helping the Terriers win promotion to the npower Championship - coolly converting his spot-kick in a nerve-wracking penalty shootout at Wembley Stadium.
