Rail strike could cost Brighton & Hove Albion £300,000
With the Seagulls having two evening matches at the Amex Stadium this week which are more than likely to be disrupted by Southern train services strikes.
The club say up to 12,000 fans travel to and from games by train to Falmer Station and that ticket sales for matches have been "slow".
Falmer Station will not be served in the evenings during the course of the strike by RMT union members.
Hundreds of Southern trains have been cancelled following a row over plans for drivers and not conductors, to operate carriage doors.
Brighton face Colchester in the EFL Cup on Tuesday before hosting Nottingham Forest in the Championship on Friday, with both matches due to kick off at 19:45.
A statement from Southern said: "[After] discussions with police, their advice is that on safety grounds no trains should stop at Falmer after 17:00 BST on upcoming match days.
"We are sorry that we cannot offer a normal service to fans. We are talking to the club about the implications for them."
As well as lost revenue totalling around £250,000, Brighton claim they will also have increased costs of £50,000 providing replacement buses, additional park-and-ride facilities and extra stewarding for the two matches.
Brighton director Martin Perry has written to three local MPs describing the disruption as "totally unacceptable".
