The Fermoy college are chasing their fourth title-in-a-row, a feat last achieved by Farranferris in 1971-'74. They will start firm favourites to reach the last four against a side who are competing at this level for the first time.
"Tomorrow's game with Colman's is very much a David v Goliath affair, but it's a game we are looking forward to. We have worked extremely hard over the last couple of weeks preparing for this game and won't be found wanting in that area," team coach Kevin McCarthy admitted.
Borrisoleigh will field two former Tipperary minors Paddy Stapleton and James Woodlock, along with David O'Connor, David Kearns and outstanding goalkeeper Mathew Ryan.
Favourites, Colman's will however take nothing for granted according to team official Ger O'Connell.
"St Josephs are something of an unknown quantity as far as we are concerned. With every game a final from now on, teams will give it everything to stay in the title race. We have no injury worries and will pick from a full squad, but we will thread warily."
Doon CBS welcome Brendan Burns and Ross Dunne back from injury for their quarter-final clash with Coláiste Spioraid Naoimh at Mitchelstown tomorrow. Doon failed at the semi-final stage last year to St Flannans and according to team official Liam Ryan, are itching for a rematch, which will materialise if both schools win their respective quarter-finals.
"If we play to our potential it will take a good team to beat us", said Ryan.
CSN with county minors, Mick Aherne, Shane O'Neill and Ronan Conway in good form, should make it to the semi-finals at the first attempt.
Midleton CBS await fitness reports on Aidan Ryan, Barry Hartnett and Evan O'Keeffe ahead of their game with Waterford Colleges at Ardmore. (1.30pm).
The participation of all three will be vital if they are to progress against a side who won all four games in the round robin series.
St Flannans face a difficult test against DLS Waterford this afternoon in New Inn (2pm). The Ennis side will have to contain the twin threats of James Quirke and Danny O'Halloran if they are to progress.
