Leeds United drew 2-2 with Derby County yesterday evening.
Wood hobbled off in the latter stages of Leeds 2-2 draw with Derby County yesterday evening, after feeling pain in his hamstring.
Evans is optimistic that the issue was just down to tiredness, although the striker will have a scan to assess the severity of the problem in the coming days.
“We’re hoping that it’s only a fatigue issue, but you never know about these for 48 hours,” Evans said.
“He’ll settle down tomorrow and then he’ll be scanned as a precaution.
“But these are the issues that we spoke about [playing twice in three days]. I wonder if Shaun Harvey at the Football League will pay Chris Wood’s wages for four weeks.
“But I don’t blame the broadcasters, who would you put on in the Championship other than Leeds? Leeds reserves?”
Wood had scored in the contest just before he was forced off with injury.
The New Zealand international got on the end of a brilliant Sam Byram cross to put Leeds 2-1 ahead against Paul Clement's promotion chasing side.
The Whites were unable to hold on to their advantage, in the absence of Wood, though - as Tom Ince struck a late leveller for the Rams.
There is a hope that Wood’s goal against Derby will help to raise his confidence.
The former Leicester City front man is yet to show his best form at Elland Road, but he put in an impressive performance yesterday.
The draw moves Leeds up to 12th place in the Championship table, while Derby sit in second spot.
