The former Watford man, who had been playing in Spain, has signed a short-term deal as cover for the missing Tresor Kandol and Neil Harris and adds a bit of depth to Kenny Jackett's squad after loan signing Jermaine Easter was sent off on his debut for The Lions last week.
"Gifton is a very talented player who at 28 still has plenty to offer," Jackett told the club's official website. "He's been abroad in recent years, but now wants to get back into English football and I'm hopeful this is the right club at the right time for him.
"He's very hungry and has enough ability, determination and personality to do very well here."
