Conor Sammon, the Republic of Ireland striker linked with Huddersfield Town, looks set to join Rotherham United.
Ipswich Town have confirmed the 28-year-old has returned to Derby County “with a view to moving on to another club”.
Nine-times capped Sammon has made eight starts and 12 substitute appearances, scoring once, since arriving at Ipswich in August.
Ipswich manager Mick McCarthy said: “Conor has not been playing and he’s unlikely to get a chance with the form of Murph (Daryl Murphy) and Didz (David McGoldrick).
“He came here to play games and he has to think about his own career and I can’t argue with that.
“He’s a great lad and has been terrific about the place but we have agreed to let him go back to Derby with a view to going somewhere else.”
The Dubliner joined Derby in a £1.2m move from Wigan in 2012.
He has notched 13 goals in 89 games (49 starts) for the Rams.
Sammon previously played for Irish sides UCD and Derry City and Scottish club Kilmarnock.
