The impish Irish forward played 10 games for the Seagulls between November 2003 and January 2004.
He's been involved in every squad since Martin Jol took over as Head Coach and appears to be closing in on his second appearance - he was set to come on at Old Trafford on Tuesday before Martin opted to throw Anthony Gardner on instead.
Mark's immediate aim is to step out at the Lane - what better scenario than against his former team-mates?
"Fingers crossed I'll be involved," said Mark at Spurs Lodge. "I was on the bench against United and almost got on and I'm hoping to get a run out on Saturday.
"I feel I'm getting closer and closer and I'd just love to go out there in front of all the home fans. It was great for Dean Marney the other day and as a young lad, that's what you want. But I'll wait my turn."
So what of Brighton? "I had a really good time down there," Mark reflected. "I was there for three months so I know the lads very well.
"Everyone knows of little Knighty (Leon Knight, pictured right). He was flying last season and scored a lot of goals. He came from Chelsea, so he has that Premier League class about him anyway.
"A lot of the lads playing now were playing in the reserves when I was down there.
"A lad Dan Harding when I was there had only played twice but he's broken in this season and taken his chance. He's been involved with England U21s and is a good lad.
"Adam Virgo was in and out, he's a centre-half whose been thrown up front and he's done the business.
"They've lost their captain Danny Cullip to Sheffield United, he was a big player and they'll miss him.
"They are coping well in the Championship when a lot of people though they might be favourites to go down but they've dug in and they are getting good results.
"They are a solid side like most in the Championship and they'll battle hard.
It will be a tough game for us."
Mark Yeates knows Brighton better than anyone at Spurs - he's hoping to face the team he spent three months with on loan a year ago on Saturday.
