Rams striker Mason Bennett fces a week of observation after a heavy clash of heads in Sunday's FA Youth Cup action against Newcastle United.
The injury to the 17 year-old hapened after just ten minutes of the Cup game and forced Bennett to leave the field and spend time in Hospital.
Bennett was fit enough to leave hospital and attend the training ground at Moor Farm yesterday but will not be able to play until next week as observations are taken of his reaction to the clash of heads.
