Trent Alexander-Arnold and Jack Grealish withdrew from the initial 26-man selection on Monday through injury, with 21 of the remaining players taking part in the full session at St George’s Park the following day.
Callum Wilson, Bukayo Saka and uncapped Levil Colwill were not involved in training due to load management, with Lewis Hall among the three prospects brought up from the England Under-20s squad to help make up the numbers.
The talented 18-year-old left-back joined Newcastle on a season-long loan from Chelsea last month, with an obligation to buy depending on performance-related criteria.
Fellow Chelsea product Bashir Humphreys was another involved. The 20-year-old defender is on loan at Sky Bet Championship outfit Swansea.
Tottenham midfielder Alfie Devine was the other to link up with the senior squad for training. The 19-year-old is currently on loan at League One side Port Vale.
