The Danish centre-half is on an initial month-long deal at The Den but has not had much of a chance to impress, having been sent off on his debut against Leicester and subsequently hit with a three-match suspension.
He returns from his ban against Sheffield United this Saturday and can also face Middlesbrough next weekend before Jackett will make a decision.
"He has this Saturday and next Saturday and then we will see if it is something we want to extend it any further," said Jackett.
