Midfielder Marcus Tavernier has completed his move to AFC Bournemouth.
The 23-year-old joins the Premier League side after spending a decade at Boro.
A product of the club's Academy, Marcus made 155 senior appearances after making his debut against Scunthorpe United in the EFL Cup in August 2017.
He scored the first of his 18 Boro goals against Bournemouth a few weeks later in the same competition and followed that with the winning goal against Sunderland at the Riverside the following month.
Marcus departs with the best wishes of all at MFC.
