Burnley had Steve Thompson sent off as they were held to a goalless draw by Championship strugglers Doncaster.
Striker Thompson was dismissed after half-an-hour for two bookable offences having clashed with Matthew Mills.
Brian Stock tested Clarets goalkeeper Brian Jensen from 25 yards as first-half chances proved hard to come by.
After the break the visitors dominated but they failed to find a way through, with their best chance falling to Paul Heffernan who fired over from 14 yards.
Burnley manager Owen Coyle:
"I can see why our player Steve Thompson was sent off.
"He was late getting over to the challenge but I don't think he actually caught the lad.
"But the player Matthew Mills that Thompson fouled shouldn't have been on the pitch at the time.
"For me, he did the worst tackle in the game on Chris Eagles and the referee gave a free-kick."
Doncaster manager Sean O'Driscoll:
"I didn't think Steve Thompson touched Matthew Mills at all for his second booking.
"But in the previous incident when they were both booked I thought he threw a punch.
"We kept possession of the ball well and competed well against arguably the form team of the league, but we just missed that killer touch."
