"He's an experienced player, played 14 games for Reading last season, he's been promoted with Reading, played in the Premier League.
"He might not be the youngest but knowing the game at centre-half level is more important."
After starting his career Iceland Ingimarsson sealed a short loan spell with Torquay in 1999.
He went on to play for Brentford, Wolves and Brighton before embarking on a Reading career which took in 281 games, 72 of which were in the Premier League.
