Richardson exits Boro
Middlesbrough defender Frazer Richardson has joined Ipswich on loan.
McCarthy has his man now, though, and he should be in contention to make his debut against former club Leeds on Tuesday.
Richardson follows Richie Smallwood, Adam Reach and Luke Williams out on loan this week.
The 31-year-old right-back has not featured under new Boro boss Aitor Karanka and signs on at Portman Road until the end of the season.
Richardson, who only joined Boro in the summer, has found a long-time admirer in Town boss Mick McCarthy who twice almost signed him when in charge of Sunderland and Wolves.
