Celtic could only managed to pick up a 0-0 draw against Hearts.
Celtic could only manage a 0-0 draw against Hearts at the weekend, but the result could have been worse if it wasn't for Ambrose's illegal intervention.
The defender hauled down Hearts midfielder Sam Nicholson, as he bore down on goal and he received his marching orders for the foul.
It was an action which saw Ambrose forced to leave the field early, but Brown believes his teammate made the right decision, by taking one for the team.
“We played really well and if we’d scored in the first-half we’d have gone on and won 3-0 or 4-0,” he said. “Craig’s not had anything to do, but we could have cost ourselves dearly right at the end.
“But it’s one of those things – Efe’s made a great team decision because if the Hearts player had got past Efe and scored a goal it would have been three points lost."
Celtic largely dominated the match against Hearts, but their lack of ruthlessness in-front of goal cost them all three points.
Leigh Griffiths was particularly guilty of missing some gilt-edged opportunities, in what was a frustrating afternoon for Deila's men.
The draw leaves the Bhoys trailing first placed Aberdeen by four points in the early SPFL table.
