Lincoln city have completed the signing of striker Jamie Clarke on a one-year contract
The 20-year-old former Blackburn Rovers struggled to make his mark with the Millers last season, having previously shown up well during a loan spell with Accrington Stanley.
Red Imps boss Peter Jackson told the club's official website: "Jamie played wide left for Accrington and down the middle for Rotherham against us last year so he will certainly give me options.
"He's got an electric turn of pace and I'm delighted to have snapped him up. He's keen, enthusiastic and looking forward to his time here at Lincoln City.
"Having been released twice over the last year or so, he's coming here with a point to prove. Hopefully I can bring the best out of him."
