The 24 year-old Danish striker left English League Two side Kidderminster only months ago after playing more than 40 times for the club. Christiansen's exit from the club coincided with the exit of then manager Jan Molby.
With the striker standing at a commanding 6'3" tall, the role of target man would no doubt be the Danish player's role at the Pars should his trial be successful.
However, on a more negative note, striker Simon Donnelly has been ruled out for up to six weeks only days after seemingly recovering from a previous injury.
After picking up a knock in Sunday's fixture against Celtic, Donnelly's stop-start Pars career will once again unfortunately be put to a halt.
Meanwhile, in other news, Icelandic winger Emil Hallfredsson, a one-time Pars target after his performances for FH Hafnarfjordur in the infamous UEFA Cup ties, is set to move to Premiership side Tottenham Hotspur.
