The sidelined winger was among players pictured at the annual fireworks spectacular hosted by Sussex County Cricket Club in Hove.
March has yet to appear on the pitch this season having made a comeback duing the previous campaign from a serious knee injury
He was pictured with Joel Veltman, Jason Steele, James Milner and Lewis Dunk enjoying one of the big nights at the 1st Central County Ground, a few hours after Albion had beaten Leeds at the Amex.
March was said to be in good spirits when head coach Fabian Hurzeler gave his most recent update.
Speaking to a recent press conference about when March could return to action, Hurzeler said: “Maybe the end of the year. He's doing well. He's progressing.
“I’ve see him running on the pitch and that's always very positive.
“I think we have to be very patient with him. It's not his first injury with the knee, but he's doing well. He's progressing well.
“He seems to be in a good mood, so hopefully he will be available by the end of the year, but I can't see in the future. So let's see what happens.”
Adam Webster is also a longer-term absentee and Albion were missing Kaoru Mitoma, Brajan Gruda, Milner and Veltman when they played Leeds.
Hurzeler will give his next update on Thursday morning in the build-up to the Crystal Palace game.
