Billy McKinlay has said West Ham did not want to take any chances over Gianluca Scamacca after the Italian striker came off injured against Fulham in a mid-season friendly.
The Italian was substituted in the 12th minute of the contest at Craven Cottage, which finished 1-1 after Jarrod Bowen struck in the second half to cancel out Carlos Vinicius' opener for Fulham.
Scamacca made his way slowly around the edge of the pitch after receiving medical treatment on the grass, following a challenge in the seventh minute from Fulham's Andreas Pereira.
