The midfielder has been training all week after recovering from a hamstring injury and is expected to be on the bench as the Shrimpers look to bounce back from the shock defeat to AFC Wimbledon in midweek.
Laird told the club's official website: "I feel fit and ready to play again so would love to be involved again, but it's up to the manager what he decides to do.
"I've trained all week and not had any reaction to the injury."
Defender Luke Prosser begins a two-match suspension after he picked up his 10th yellow card of the campaign in the 3-1 defeat to the Dons, while Danny Mayor has returned to Sheffield Wednesday after his loan spell expired.
Paul Sturrock remains without the injured Gavin Tomlin (thigh), Mark Phillips (broken toe) and Chris Barker (Achilles).
