Boro's Under-23s started the week on the south coast and they end it there aiming to reach the Play-Off final.
Brighton's Amex Arena is the venue for this one-off tie, with the winner taking on the either Aston Villa or Reading. The Play-Off winner will join champions Blackburn, promoted earlier in the week, in the first division of the PL2 next season, replacing relegated Manchester United and Sunderland.
There was little to separate Boro and The Seagulls throughout the year, with just three points between the sides at the end of the regular season that concluded for us with a 2-1 defeat at Southampton on Monday. Brighton ended third, one place above us.
Brighton are on a storming run, unbeaten in eight, 15 if cup games are taken into account, including a 3-0 win against us at Bishop Auckland, scoring five in each of their last three.
We have been in the top five pretty much all this campaign, top for long spells, and it was only the period of readjustment when several players went on loan at the same time where form dipped slightly.
"We're ready to give this a right good go," says Lead Coach Paul Stephenson. "We deserve to be where we are, we're here on merit. So are Brighton, we saw how effective they are a few weeks ago.
"This should be a cracking game in a very good stadium and we're very much looking forward to it."
Kick-off is 7pm and entry is £5.
