Dorsey came through an intense battle with Thomas Davis in the opening round of the championship.
One-point was the difference between the sides after a hugely entertaining encounter two weeks ago.
That win and the momentum it brings makes them favourites on Sunday when they meet Redmond O’Hanlon’s.
Both sides will see this as a massive opportunity to reach the last four of the Junior Championship.
Dorsey last reached the semi-finals two seasons ago, when they were downed by eventual champions Collegeland.
Last season, Seamus Loughran’s men lost out to Belleek in the quarter final stages of the competition.
O’Hanlon’s on the other hand fell at the first hurdle, narrowly losing to Cross IIs by two-points.
The split in the Junior league separated the sides, but really there were only four places between them.
Redmond O’Hanlon’s finished second in Junior B, just behind the league winners St Michael’s.
The Emmets on the other hand ended finished in 6th position in the top end of the Junior league, winning 8 of their 18 games.
Aidan Mackin was the star of the show the last day out in the green and yellow, striking 1-5 to see off Corrinshego.
Conor Moley is a powerful midfielder, and the Dorsey defence would have been happy with their clean sheet two weeks ago.
Charlie Magill is the star man for O’Hanlon’s and will offer a huge scoring threat in their attacking half.
Captain David Hudson will lead from the defence as they try to restrict the oppositions scoring chances.
Dorsey won the league clash between the two sides back in June, 1-15 to 0-7.
This game could go either way, but Dorsey’s momentum from the last day out could be enough to guide them over the line.
