Nigel Pearson admitted he may be forced to switch to a back four for Saturday's trip to Birmingham after Kal Naismith hobbled off with a calf injury in the draw with Coventry.
The centre-back was forced off five minutes before half-time after appearing to pull up when overstretching in a challenge. Without a recognised central defender on the bench, midfielder Andy King dropped into the heart of the back three and performed admirably in an unfamiliar position.
Coventry arguably had the better of the chances in a tight game with Dan Bentley denying striker Viktor Gyokeres on the hour mark after the striker was played through on goal. The City stopper also denied Kasey Palmer at the beginning of the second half as the Robins ended their three-game losing streak.
