However, the 23-year-old is now nearing a return to fitness and is expected to resume full training soon.
"I am very happy about this," Laszlo told the club's website. "I hope this means we have very few players injured. If Tullberg is back then this gives us a bit extra and more options for us."
Laszlo is particularly looking forward the potential partnership Tullberg could form with Christian Nade in attack when he returns.
"We have not seen him together with Christian Nade, because they have not been both fit at the same time," he added.
"However, this is something we will consider."
