Stephen Curry is officially day-to-day with a bone bruise in his ankle — and considering this is their star player with a long history of ankle issues (including multiple surgeries), you can expect the Warriors will be cautious here. Even though Curry said Wednesday he expects to go Friday night against the Spurs.
However, Curry wasn’t at shootaround Friday, reports Rusty Simmons of the San Francisco Chronicle. It is very possible Curry is out and Toney Douglas will get the start for the Warriors.
