Portsmouth and Wycombe Wanderers have been unable to find the net in a goalless first half at Fratton Park.
Wycombe dominated in terms of chances but accuracy was lacking as only two of their 10 shots were on target.
Pompey's only notable chance fell to Patrick Agyemang inside the box, but it was Wycombe's Danny Rowe who reacted quick enough to deny the striker.
Wycombe will look to continue their pressure throughout the second half, with manager Gareth Ainsworth hoping for his side to convert one of their many chances.
