An Anthony Stokes penalty in stoppage time rescued a point for Scottish Premier League leaders Celtic as they were held to a 1-1 draw away to bottom club Hamilton, who ended with nine men on Wednesday.
Simon Mensing was hero and villain as he fired Hamilton into a 27th minute lead before seeing red in injury time as he conceded the penalty which cost his side all three points. There was a hint of offside when Mensing headed the home side ahead before Celtic's James Forrest was sent off for a late challenge just after the break. Hamilton substitute Jim McAlister lasted just 35 seconds on the pitch before he saw red in the 64th minute for a dangerous tackle on Mark Wilson.
Freddie Ljungberg made his debut from the bench but it was Stokes who levelled the scores from the spot after Mensing brought down Emilio Izaguirre in the box. The Irishman then had the ball in the net again six minutes into injury time when he headed Izaguirre's corner past Tomas Cerny but the ball was adjudged to have gone out before reaching him.
The point extends Celtics lead over Ranger to five points, albeit their rivals have three games in hand.
Celtic came close when Paddy McCourt went on a mazy run to the by-line and sent a cut-back to Forrest but he delayed too long and his shot was charged down. However it was bottom club Hamilton who took a shock lead. Hasselbaink won a free-kick on the left-wing in line with the six-yard box which Flavio Paixaio whipped in.
The ball ricocheted off Forster's shin but Mensing was quick to react and sent a looping header into the bottom left-hand corner, much to the anger of the Celtic bench who felt Martin Canning had been in an offside position interfering with play as the free-kick came in.
Things got even worse for Celtic three minutes into the second-half when they were reduced to ten-men. David Buchanan cleared the ball up-field and Forrest steamed in with a late challenge that caught the Hamilton player's trailing leg and earned a straight red from referee Willie Collum.
Hamilton brought on Jim McAlister for Mark McLaughlin in the 64th minute but the winger lasted just 35 seconds on the pitch as he lunged into a dangerous late tackle on Mark Wilson to also see red.
