Welling defender Tony Sinclair has been given the all-clear after being stretchered off in Monday's Bank Holiday win over Fisher.
Sinclair, who missed most of last season with a knee injury, was injured in the first 10 minutes and taken to hospital with a back injury.
But Wings boss Andy Ford said: "It may have been a muscle spasm but Tony got a kick in the back and had pain down his leg.
"He will probably be sore for a few days and is likely to miss the next couple of games.
"It's not as bad as it could have been but we'll know more by the weekend."
With Sinclair ruled out, Ford is hoping that defender Graeme Andrews (dead leg) will be fit for the weekend's Blue Square South trip to Hayes & Yeading.
