Mark Weideman presumably would have been very unhappy about being left out of the 1981 Grand Final team, having been in the Preliminary Final side and playing 20 games that year. With Peter Moore returning for the GF he lost his spot in the team. The fact that he stayed at Collingwood for another 3 seasons suggests he handled the situation okay.
I'm pretty sure he had quite a few injury problems, I just can't find any real evidence of that. He was sold to Fitzroy after the 1984 season, but failed to play a senior game there. I presume that injury hampered him at the Lions at least. Strangely, the biography on his Collingwood Forever page only mentions that he went to Coburg (this is an exact copy of what it says in Encyclopedia of AFL Footballers):-
Son of Murray, he was recruited from West Adelaide, but never established a regular senior place and later transferred to Coburg.

Moore on the other hand never recovered from the ignomy of playing injured in that finals series and costing us a premiership, and left for Melbourne. All forgiven now though!
