Substitute Bryan Gilfillan scored a late equaliser as Peterhead rescued a point in a 1-1 draw at home to Brechin.Chances were at a premium in a poor first half, with neither side able to create many genuine opportunities on goal.The hosts were forced into a reshuffle just after the half-hour mark when the injured Scott Ross was replaced by Dean Cowie.The second period looked to be following suit before Alan Trouten broke the deadlock for the visitors, slotting home after some good work by Andrew Jackson in the 64th minute.The visitors could have been further ahead soon after had Trouten's effort not come back off a post and they were left to rue that wasted opportunity when Gilfillan ensured a share of the spoils as he popped up two minutes from time to finish from close range.
