The January transfer window comes to a close 11pm on Friday and Forest boss Sabri Lamouchi remains keen on improving his defensive options.
His side are currently unbeaten in the league in 2020, winning three and drawing two, but keeping only one clean sheet in that time.
And the Forest boss has reportedly set his sights on the Brighton defender as a solution to their defensive frailties as they continue to aim to secure a play-off spot.
The Midlands outfit will also be keen to bring in defensive options following the sale of defender Jack Robinson to Sheffield United and with centre-back Chema Rodriguez returning to Spain, according to Spanish outlet Cadena Ser.
Bong has struggled to find his way into Graham Potter’s side so far this season, featuring seven times in all competitions.
But the Cameroon international would be an ideal signing for Lamouchi’s side, as he has a wealth of experience in the top flight and will be desperate for regular, first-team football.
The 31-year-old played a vital part in Brighton’s promotion to the Premier League in 2017, and knows what it takes to stay in the top flight.
Having played over 100 games for the Seagulls, the defender is reportedly pushing for a move away from the club having fallen out of favour on the south coast.
