TWTD understands that former Watford, Leicester, West Brom and Millwall winger Lloyd Dyer will join the Blues on a deal to the end of the season. The 33-year-old’s contract at Vicarage Road was terminated by mutual consent last week.
Birmingham-born Dyer began his career at the Hawthorns and spent time out on loan at Kidderminster, Coventry and QPR before signing for the Lions in 2006.
He moved on to the MK Dons for two seasons before signing for Leicester in 2008 and helping them to the 2013/14 Championship title.
The 5ft 8in tall wideman moved on to Watford that summer, signing a three-year deal, but made only six starts and 10 sub appearances for the Hornets last season, scoring three goals.
In January last year he went out on loan to Birmingham, where he made eight starts and 11 sub appearances and netted once. Having not been involved at all this season he left Vicarage Road last week.
"We understand Dyer will put pen to paper on a deal to the end of the season on Tuesday.
Blues boss Mick McCarthy was looking for an additional left-sided winger even before Ryan Fraser suffered his hamstring injury during Saturday's 1-0 defeat at QPR with Tommy Oar having left Portman Road at his own request last month.
Former Arsenal and Charlton man Jerome Thomas spent a week training at Playford Road but wasn't offered terms. Town are likely to announce how long Fraser will be out of action today.
