ALL-Ireland league champions Cork Constitution must plan without out-half Aidan Moynihan for the foreseeable future after he suffered a serious leg injury at the weekend.
One of the league's leading marksmen, Moynihan was injured early in the 13-10 away win over Terenure College in dreadful conditions of driving wind and rain on a pitch that cut up badly.
The holders fought back from 0-10 thanks to a penalty try and penalties from Jack Crowley and Sean French, who landed a monster kick to snatch the spoils.
Crowley, a member of the talented Bandon Grammar School side, which reached the Munster Schools Senior Cup semi-final last season, took over Moynihan's role, having started at full-back on his league debut.
Now, the youngster is in the frame to wear 10 against Trinity College at Temple Hill on Saturday.
Con, who took over leadership of division 1A from UCC, have other injury issues as well, including captain Niall Kenneally, JJ O'Neill, Greg Higgins and Tomás Quinlan.
College are also badly affected by injuries following their first defeat of the campaign, when going down 27-20 at home to Clontarf.
Already missing out-half James Taylor and centre Cian Bohane, the students were left sweating on the fitness of second-rows Richard Thompon and Cian Barry along with wing Matthew Bowen.
None finished the game and are in a race against time for the visit of the second-placed to Terenure, in third, on Saturday.
Taylor and Bohane suffered knee injuries against Young Munster and Ballynahich respectively and are out of commission for a while.
UCC's defeat leaves Con and Highfield as the only unbeaten Cork clubs across all five divisions.
Field sit top of division 1B following their 16-11 win over St Mary's in Dublin and now turn their attentions to playing another club from the capital, Old Belvedere, at Woodleigh Park on Saturday.
Highfield are aiming for a fifth successive victory in their first season in the division as they attempt to claim successive promotions under the direction of player-coach Timmy Ryan. Shane O'Riordan has kicked 39 points.
