However, the Warriors and Curry chose not to test the ankle.
For Bucks fans, the news could be good or bad--depending on the point of view.
On one hand, fans with tickets will certainly be disappointed without the dynamic Curry in action, but on the other hand, his absence could mean a crucial win for a Bucks' team fighting for playoff contention.
In his 14 career games against the Bucks, Curry has averaged 20 points, 6 assists, and has shot 40 percent from 3-point range.
Plus, over the course of the season the Warriors offensive rating is 13 points higher when Curry is on the floor.
Even without Curry, Bucks fans should expect an entertaining game on Friday versus the NBA best 33-9 Warriors that features all-stars Giannis Antetokounmpo, Kevin Durant, Klay Thompson and Draymond Green.
It will be an important test for the 21-18 Bucks who are currently sixth in the Eastern Conference.
It will also be an important bounce back for the Warriors who fell to the Clipppers 125-106 without Curry and Thompson.
