Monk Out For 3 More Games
Captain and defender Garry Monk will miss another 3 games because of a back injury.
He was expected to return on Friday afternoon when the Swans travel to Southend but he has suffered a further setback.
Obviously it's a blow to the Swans as Kristian O'Leary is our only available back-up defender.
Martinez is confident Lawrence can play on Friday after twisting his ankle during last night's 2-0 win away at Bristol Rovers.
