Glas and Kullberg have tested positive for covid-19, while the national team, for tactical reasons, does not want to say whether Jonna Andersson's test was also positive.
Whether the trio will have time to recover for tonight's meeting with Belgium is unclear.
Gerhardsson says that all three ran soccer drills individually during yesterday.
- We will see how it goes.
We always have a plan on how to act.
What causes it a little is that it is the same type of player, full backs.
There you have to think a little extra.
But we must be solution-oriented instead of feeling sorry for ourselves, he says.
Glas and Andersson have been regular outside backs in the team, while Kullberg has trained as a right back.
Gerhardsson still sees stronger replacements in the team if needed.
- We have options and some players who can play in different positions.
