Coleraine and Larne shared the points after a closely contested NIFL Premiership meeting ended 0-0 at the Showgrounds.
Larne were forced into an early change when Jordan McEneff replaced Daniel Bent in the 14th minute. Aaron Donnelly was booked later in the first half, while Joel Cooper received the visitors' next yellow card five minutes after the restart.
Both managers turned to their benches as the search for a goal continued. Aidan Wilson replaced Rowan McDonald for Larne in the 59th minute and was booked two minutes later, while Coleraine introduced Conor McKendry and Conor McMenamin during the second half.
The deadlock remained intact through the closing stages, giving both sides a clean sheet and a point from a 0-0 draw.
Coleraine had opened their league season with a 3-1 victory at Dungannon Swifts. They travel to Carrick Rangers in their next scheduled Premiership fixture on Saturday 22 August.
