Minnesota United began preseason training this week with most of its rostered players participating, but without Ike Opara, the two-time MLS Defender of the Year.
Loons coach Adrian Heath earlier expressed optimism that Opara, 32, could return to play this season. He didn't sound that way Wednesday.
"Ike was feeling particularly good at the time, but at the moment he's not feeling particularly good," Heath said. "We're taking the situation week to week and see where we are and how he is. At the end of the day, we're governed by how he feels.
"This is not something we can talk to him about and tell him he has to work through the pain. He has a situation only he can tell us how he feels. We're obviously guided by that."
Opara hasn't played since this time last year because of an undisclosed condition that limited him to two games played at the start of last season.
Heath called Opara's situation a "bit of frustration for all of us. We still have to live in hope we'll get where we all want to be. But it's looking a bit different at the moment."
Heath said there's no deadline to determine Opara's playing future.
Waiting game
Star midfielder Emanuel Reynoso, newly signed striker Juan Agudelo, Ozzie Alonso and New Zealand defenders Michael Boxall and Noah Billingsley trained individually while they finish travel quarantines.
