Wycombe Wanderers and Fulham remain goalless at half time of their League Cup first-round meeting.
Ross McCormack almost put Fulham ahead early on, but his shot from inside the box flew inches wide as the Championship side made a confident start.
Joe Jacobsen had the hosts' first chance of the game with a volley from 30 yards which went over the bar, while Garry Thompson missed from close range after Anthony Stewart's knock-down fell for him in the box.
Fulham thought that they had taken the lead five minutes before the break when Alex Kacaniklic found the top corner with a thumping strike, but it was ruled out for offside.
