Young forward Iffy Allen will miss the start of the season after suffering a broken leg in training and will be sidelined for the next six to eight weeks.
Allen, 20, sustained a fracture of the fibula in a training ground collision earlier this week and, as a result, will be out of action for the next six to eight weeks.
The Lambeth-born forward was able to walk off the training pitch following the injury and later went for an x-ray to ascertain the extent of the damage.
Speaking to the club website, Martin Allen said: “All the players are fit and well apart from young Iffy Allen who had a collision tackle a few days ago and has a fracture of his fibia bone, in effect what you could call a broken leg in the old days.
"Iffy has come back in really good shape, very strong, very positive and has clearly trained through the summer."
Allen added: "He walked off the training pitch and it was only later in the evening where the pain really set in so sadly this weekend we are going to be without Iffy but that is our only injury.”
