Town have decided not to lodge an appeal against the red card skipper Luke Chambers was shown in Sunday's 3-2 final-day victory over Leeds United at Portman Road.
Chambers, 33, was dismissed in the 79th minute for felling Whites striker Kemar Roofe inside the penalty area with the former Oxford man blazing the spot-kick over the bar having lost his footing as he struck the ball.
Speaking after the match, manager Paul Lambert said the Blues might consider appeal under the double jeopardy rule which states that players committing an unintentional foul - the incident appeared more a tangle of legs than a deliberate trip - should only be yellow-carded if a penalty is awarded.
However, the Blues have now opted against an appeal, which could potentially have resulted in a further ban if dismissed, and Chambers will be suspended for Town’s opening game in League One, which will be played at some point over the weekend of Saturday 3rd August.
