The on-loan Albion winger is among the nominations for EFL League One young player of the season after a sparkling campaign before injury struck.
He has also returned after a lengthy lay-off and went on as substitute in the closing stages of the 2-2 draw at home to Stockport on Easter Monday.
The former Arsenal youngster was introduced on 72 minutes and helped his side come from 2-1 down for a point.
They look set for the play-offs, which will give the 20-year-old more chance to impress when the stakes are high.
Before that, Wanderers visit second-placed Cardiff knowing a win might just help them chase an automatic play-off spot behind Lincoln City.
They trail the Bluebirds by seven points and have a much inferior goal difference as well as having played a game more.
In reality, an end-of-term semi-final, possibly against Stockport again, is looking highly likely.
Cozier-Duberry was arguably the most exciting player in the third tier until he suffered knee ligament damage in January.
He made a speciality of important late goals and was a particular threat cutting inside on to his left foot.
Bolton boss Steven Schumacher said: “We were a bit light in the squad so we thought, ‘Right, there’s a spot on the bench and hopefully it will give the crowd a bit of a lift too’, which it certainly did.
“It was lovely to have him back on. It's going to take him a bit of time to get up to his full rhythm, but when he does, we all know how good of a player he can be.”
Cozier-Duberry, who turns 21 next month, has six league goals plus eight assists so far this season.
