The 29 year old son of former City striker Ronnie is said to be close to a move to Ninian Park.
Moore junior has twice been sold for £1m in his career which has seen him play for Tranmere, Bradford, Forest, West Ham, Stockport, Burnley and since March 2005 Leeds Utd.
Last season he failed to score in 22 games but most of those were off the bench. His best spell came at Burnley when he scored 37 goals in 170 league starts.
