Now the £700k midfielder from Luton faces a race against time to be fit for Leeds' first Championship fixture at home to Norwich next Saturday.
Also missing the Forest friendly will be left-back Stephen Crainey, midfielder Shaun Derry and striker Richard Cresswell, who are all carrying injuries and have not played in any pre-season games. Eddie Lewis is expected to feature however after his World Cup exploits with the USA.
Trialist defender Hayden Foxe, meanwhile, has had to return to his London home for personal reasons. Kevin Blackwell will get a further chance to plan his opening-day in another friendly on Monday at Grimsby.
