2000 premiership player Scott Lucas remains in doubt for the blockbuster Friday night match between Essendon and Richmond. The centre half forward walked three laps of the MCG at Essendon's training this afternoon before leaving the track. Essendon coach Kevin Sheedy told the media at training that Lucas is a 50/50 chance of playing in the round two match. A full transcript of Sheedy's press conference will be available on the BomberLand site later today.
