Sweden captain Zlatan Ibrahimovic has emerged as an injury doubt for Thursday's Euro 2016 qualifier against Russia in Solna.
The striker missed training on Tuesday due to the heel problem that has seen him miss club Paris Saint-Germain's last four games.
"For the moment, I am injured," the 33-year-old is quoted as saying by Sky Sports News. "But I'm on my way back and doing recovery for the moment. It feels good and it is going in the right way."
Sweden currently sit in third place in Group G following a 1-1 draw with Austria in their opening match of qualifying.
