Notre Dame forward Luke Harangody said he hurt his knee after Thursday's 90-87 road loss to Seton Hall.
Harangody said he injured his left knee coming down for a rebound with 8:42 to play, but he said he was told not to worry.
"I think we have to see how it feels tomorrow," Harangody told the AP. "The trainers checked it out and they told me that I shouldn't worry about anything. It could be just a sprain. It feels a lot better now."
The injury appeared to be to his ankle, according to The Associated Press' intial report.
Harangody, who was averaging 24.5 points and 10.1 rebounds, sat at the end of the Notre Dame bench in the final minutes with a towel wrapped around his neck.
"At first, I thought it was his ankle, but it was his knee," Brey said. "He tried to give it a go, but he said it was sore. I think we did a heck of a job without him. We hadn't played much without him all year, but in the end, we had a fighting chance. I don't anticipate him being out long. We'll see where we're at tomorrow. We'll ice him down and take a better look at it tomorrow."
Harangody's 13 points gave his 1,324 in the conference, moving him into third place overall ahead of Seton Hall's Terry Dehere (1,320). Troy Bell of Boston College is No. 2 in conference scoring with 1,388 and Syracuse's Lawrence Moten is No. 1 with 1,405.
