Former Biggleswade Town and St Albans City man Andrew Iwediuno is the new face in the Saints squad. He has been at Hendon in the early part of this season. Iwediuno trained with the club last night and is likely to feature in a Southern League Premier Division home clash against Tiverton at ProEdge Westwood Road tomorrow, 3pm. But as one new defender arrives, another one has headed through the Saints exit. Veteran Lee Chaffey has been released after 15 months with the club. Andrew is a player we were first alerted to in the summer, but hed already received other offers by then, said boss Ricky Marheineke. Weve been keeping tabs on him for a while and now is the perfect time to get him in. Its no secret that we need to tighten up defensively after conceding far too many goals so far this season. Its always sad to have to release a player, especially one as committed and professional as Lee. Ive got the utmost respect for what he has achieved in the game, but we reached a point where we felt we had to part company. Were looking at bringing in other players in the coming days, but this is not a process we can rush. Its one we need to get right. Marheineke comfirmed another defender, Carl Langa, who made his debut in a Monday drubbing at the hands of tenants Cambridge City in the Southern League Challenge Cup, wont play for the club again. Saints have received a double injury blow ahead of their clash against Tiverton tomorrow. Jimmy Hartley suffered ankle ligament damage when appearing as a late substitute against Cambridge City and fellow wideman Phil Draycott then rolled an ankle in training last night. Saints have only managed one win in their first 10 league games and that came on the opening day of the season. They sit third-bottom of the standings after picking up just five points during a difficult start to the campaign. The fixture against Tiverton falls on Non League Day - an annual initiative during an international weekend when there are fewer than usual professional games taking place. Saints are offering half-priced admission to any supporters able to produce a valid season ticket from another club. Fellow local sides Godmanchester Rovers (against Thetford Town in the Thurlow Nunn League Premier Division) and Huntingdon Town (against Lutterworth Athletic in Division One of the United Counties League) are also at home tomorrow.
