Town recorded their fifth successive home draw at the start of the season as Bolton Wanderers left Portman Road following a hard-fought 0-0 stalemate, despite having been a man down for 47 minutes. The Trotters lost Marc Wilson to a red card on 34 after he hauled down Kayden Jackson but the Blues only created one serious chance - a Luke Chambers header brilliantly saved by Ben Alnwick - having been reduced to 10 men themselves late on when Jon Walters suffered an injury with all three substitutions already having been made.
