Midfielder is fit and ready to battle for first-team place
The Wales international has been training with Blues for a few weeks and has now put pen to paper on a deal that will keep him at the Club until the end of December.
“There is a good squad here and a lot of competition for places so I know it will be no easy task to get in the side,” the midfielder told Ipswich Player.
“It’s down to me to get my head down and work hard and impress the manager enough for him to give me a chance in the team. Then I’ve got to take that chance.
“In the short space of time I’ve been here I have enjoyed working with the players and the manager. There is a good feel about the place and everyone knows what a great club Ipswich is.
“I’m here until the end of December and we will see what happens after that. All I am focused on at the moment is getting back to playing football again, enjoying my football again and getting in the team.”
Jack, who had seven years at West Ham before leaving in the summer, spent loan spells at Wigan and Bournemouth last season after injuries hindered his progress at Upton Park.
“It’s been well documented about my injuries over the last few years,” added Jack.
“I’m feel fit now though and ready to go. It will take me a couple of weeks before I’m knocking on the door but I’ll be working hard and doing my best to get in the team.”
