The defender missed the Petrofac Training Cup victory over Hibernian last week and Sunday's Championship defeat to Hearts after being sent off in the pre-season friendly against Derby County.
It has not been a great start to the campaign for Mohsni, who had a mixed tour of North America as Ally McCoist's side struggled in their summer fixtures.
In his absence, Lee McCulloch, Darren McGregor and Marius Zaliukas have all appeared at centre-back for the Light Blues.
But with Richard Foster injured and boss McCoist in desperate need of a result, the 27-year-old could come back into the team to face the Bairns as Rangers look to get back on track tonight.
Mohsni said: "I've been doing extra runs with sport scientist Jim Henry which has helped.
"I've been able to get fitter and hopefully I can now go and show that is the case out on the pitch in matches.
"Of course, I would have preferred to have been playing lately but the fact I haven't been means I have been able to work more on my fitness.
"In pre-season, I lacked concentration at times. Maybe that is because I came back late, I don't know.
"I'm not looking for excuses though. I felt I needed to do extra work and I feel much better now so I am looking to do well if I get the chance to play."
