It was reported Monday that Baldwin would miss time with a partial MCL tear. Carroll claimed the team didn't report a tear, but said his top wideout is having "MCL issues," per USA Today's Andy Patton.
"He's really gonna go a few days at a time here," Carroll said Tuesday, via ESPN's Brady Henderson. "Let's see what happens. We'll wait and see. We don't know yet. It could be a couple weeks. It could be a couple weeks, and we'll find out. He's as tough as you get. We'll need to wait."
Baldwin dealt with recurring left knee problems throughout the preseason, but his current injury is to his right knee.
A lengthy spell on the sidelines would be a big blow to the Seahawks' passing attack, as Baldwin was the team's leading receiver in 2017.
Seattle is set to battle the Chicago Bears in Week 2.
