David Mooney is in line for his full Leyton Orient debut against Wycombe.
The striker, a summer signing from Reading, missed the start of the season with a hamstring injury but came on as a substitute against Tranmere on Saturday.
With the Os yet to find the net in their two league matches so far, Mooney is set to start in attack alongside either Jamie Cureton or Alex Revell.
Former Millwall midfielder Marc Laird was an unused substitute at the weekend after a thigh problem and is also pushing to make his debut.
French forward Jonathan Tehoue serves the second game of his three-match ban for his red card against Southend last week and midfielder Leon McSweeney (knee) and goalkeeper Jamie Jones (shoulder) remain sidelined.
Elliot Benyon will be hoping to make his first start for Wycombe.
The striker, on loan from Swindon, made his long-awaited Wanderers debut at Colchester on Saturday following several weeks out with a broken hand.
Blues boss Gary Waddock has no new injury or suspension problems. Matt Bloomfield (groin) remains touch and go but with the midfielder being so close to a return, Waddock could opt to keep him back for the home game against Bury at the weekend.
Kevin Betsy is due back from the Seychelles after missing the first three matches of the season helping his country to win the Indian Ocean Games. However, it could be too late for the winger to be involved.
Stuart Lewis has made progress in his recovery from the virus that has ruled him out so far this season but he is still some way off being considered for the first team.
Meanwhile, 19-year-old striker Matt McClure is expected to return to Wycombe from his loan spell at Hayes & Yeading after suffering a dislocated ankle whilst making his debut for the non-league club on Saturday.
