"McBride.... insisted that Cotton had put a Jelly-Fingers curse on him as they both swooped down on the Snitch"
-- match report in the Daily Prophet (DP3)
Dougal McBride played Seeker for the Pride of Portree Quidditch team (DP3).
After a scuffle in the air, he lost the Snitch - and therefore the match - when (according to McBride) Appleby Arrows' seeker Gregory Cotton cursed him. McBride then turned Cotton's head into a cabbage in retaliation. The referee found that both Seekers were flying with illegally concealed wands and an enquiry will follow (DP3)
While the date printed on DP3 is 1 June 1999, the timeframe for these events is 1992-1993.
