Minnesota United was a man short in its last practice before facing Sporting Kansas City at 12:30 p.m. Sunday at TCF Bank Stadium.
Starting right-back Jerome Thiesson was the missing piece Saturday at the National Sports Center.
"He's been feeling a little bit under the weather, so we didn't want to [push him]," coach Adrian Heath said. "We'll know more about him in the morning."
Thiesson has started and played 90 minutes of every match since he's been here, joining the team shortly before the second match of the season against Atlanta United.
Heath also discussed the end of MLS' primary transfer window coming up on Monday. That deadline is the last opportunity for United to sign an international player on a transfer until the next window opens later this summer. The team could still acquire people that are out of contract or domestic players, however.
"We had a few things bubbling under early on in the week, and it's gone a little bit quiet," Heath said. "So unless something happens today, I can't really see anything happening."
