Leeds United boss Marcelo Bielsa is not sure about the extent of the injury suffered by midfielder Kalvin Phillips.
The defensive midfielder is a key player for Leeds, and is a recent member of the England squad as well.
He sustained a shoulder injury against Wolves on Monday in the Premier League.
While initial reports mentioned a six week layoff, Bielsa was hesitant to commit to a timeline.
Bielsa told reporters: "I don't have the definitive amount of time that Phillips is going to be out for. I understand that the information is incorrect. It could be more, or it could be less."
