De Goey, who turns 23 this month, has been progressing well following concerns of a foot-sprain three weeks ago.
Buckley believes he is still pushing for selection after it was revealed De Goey avoided any serious injury following the training mishap.
“He’s actually come out of it really well,” Buckley told SEN’s Time On.
“The initial scans were encouraging.
“To see him straight-line run last Thursday was good.
“(He) came off the line a little bit on Saturday and did some football drills on Monday, so he’s pushing to prove his fitness for Round 1, and that’s still over two weeks away.”
Buckley credited the club’s fitness team, who are doing everything they can to allow the star forward to play early on.
De Goey, who booted 48 goals from 21 matches last season, won’t feature in the final match of the JLT series against the Blues on Monday night, but will be a vital inclusion for the blockbuster round one match-up.
