The injury-depleted Chicago Bulls are facing an unexpected early elimination from the NBA playoffs.
The team with the best record in the Eastern Conference, are now 3-1 down in their best of seven series with the Philadelphia 76ers, after an 89-82 loss in game four.
The Bulls forward Taj Gibson says they can't use injuries to important players such as All Star guard Derrick Rose and centre Joakim Noah, as an excuse for how they've played.
Game five is in Chicago on Wednesday.
