Orient set for big cash boost

The O’s also stand to pocket a potential further ?170,000 in

add-ons from the Championship club and will recieve 16.5% of any

future sale.

Porter made 38 appearences for the O’s last season, mainly as a

substiute, after joining from non-league side Cray Wanderers.

The 20-year-old rejected the offer of a new contract at Brisbane

Road and signed a three-year deal at Turf Moor in July.
