Mansfield Town striker Ollie Palmer has put pen-to-paper on a two-year contract with Sky Bet League Two newcomers Leyton Orient after being sold from the Stags for an undisclosed fee.
The 23-year-old spent two seasons at One Call Stadium and scored seven goals in 64 appearances.
He finished the 2014/15 campaign on loan at Vanarama Premier side Grimsby Town, for whom he made 16 appearances – scoring on eight occasions.
Stags manager Adam Murray said: “We have come to an agreement with Leyton Orient that we feel is a good deal for the club.
“It was a move which Ollie wished to pursue.
“We thank Ollie for his efforts whilst with us and wish him every success for the future.”
