Town are reported to be closing in on the signing of Mikele Leigertwood, who was released by Reading at the end of last season.
The 31-year-old began his career with Wimbledon and has since spent time with Leyton Orient (loan), Crystal Palace, Sheffield United and QPR before joining the Royals, initially on loan in 2010, prior to signing a permanent deal in June 2011.
Londoner Leigertwood scored the goal which took Reading into the Premier League in 2012 but last season he was limited to three starts and one sub appearance having undergone ankle surgery at the beginning of the campaign.
The midfielder, who is 6ft 2in tall, has won 11 caps and scored two goals for Antigua and Barbuda.
Town boss Mick McCarthy is likely to be keen to add to his options in the centre of midfield with loanee Paul Green having left the club at the end of the season and not having been offered terms for the season ahead.
