Stephen Curry is optimistic his injury recovery is going well, but vowed to stay cautious and remains unable to pinpoint exactly when he will return to the court. The Golden State Warriors star has missed the last five matches with a groin strain and will also be absent when the defending NBA champions take on the San Antonio Spurs on Sunday. Curry is back doing individual drills and will be re-evaluated in around a week, the Warriors having lost three of their last four matches with the two-time league MVP absent.
