34 year old Wood limped off during Saturday's 3-1 triumph over Maidenhead after 37 minutes with a hamstring problem.
He was due a scan today to asses the damage, but speaking after the game, boss Paul Warne was'nt optimistic"It will be three to four weeks at least, The scan will show how severe it is."
With Woody out, Warne is pinning his hopes that Clark Robertson returns to fitness this week after spending time on the sidelines
"Hopefully Robbo will join in training next week, "He needs to because I'm going through my players at the back like water at the moment. I've already lost both left-backs. I've lost a centre-half today. It's a bit of a concern.
"I don't think Robbo will be ready in time for the Lincoln game, We might have to play a different system to accommodate the disasters." Warne added.
