Lincoln City defender Lee Beavers has admitted the Imps' lapses in concentration have cost them dearly in League Two this season.City have the second worst defensive record in League Two and were on the wrong end of a 4-0 hammering by Peterborough at the weekend.

The loss was the ninth time this season that Lincoln have gone down by a margin of four or more goals and Beavers has blamed a lack of discipline in the Imps' backline for the problem.

"Towards the end of games we've allowed teams to get fours and fives too often. Its not acceptable," he told the Lincolnshire Echo.

"We shouldn't be letting in those goals, we have to learn to defend better for 90 minutes."
