Lincoln manager Chris Moyses has said he is "pretty disgruntled" by striker Liam Hearn's decision to join National League rivals Barrow on loan.
Hearn asked to join the Bluebirds in order to "maximise his game time".
The 30-year-old has made 18 appearances for Lincoln since signing from Mansfield in July, scoring eight goals.
"I actually think we've looked after Liam quite well as a football club, we've got him going again," Moyses told BBC Radio Lincolnshire.
"We've been careful with how we've treated him and the times that he's played and not put him at any risk whatsoever.
"We had nowhere to go to try and get someone back and I feel pretty disgruntled at the moment.
"I couldn't predict that one coming at all, and it hurts me to a degree that I thought I knew people and I don't."
