Town have confirmed that Crystal Palace's Jonny Williams has rejoined the club on a season-long loan, his fourth stint at Portman Road.
Williams, 22, initially joined the Blues in February 2014 and became a big fans' favourite during the remainder of that season.
The Pembury-born midfielder, who is contracted to Palace until 2018, returned in the following September but had his spell curtailed by a thigh injury suffered in the Watford game in the November.
He came back to Town for a third spell late in that season but made only two sub appearances before suffering a recurrence of the problem in an U21s game.
Williams, who played for Wales at the European Championships in the summer, spent time on loan at Nottingham Forest and with the MK Dons last season.
He suffered an ankle injury in pre-season but is expected to be fit to play in October.
