Derby County's Nathan Tyson suffers fresh injury delay
Injury-hit Derby County striker Nathan Tyson's return has been delayed again.
Summer signing Tyson has only played 25 minutes of first-team football for the Rams because of a groin injury.
He was forced off in the first half of the pre-season game against Aston Villa but featured as a substitute against Nottingham Forest last month.
However the 29-year-old forward then needed minor surgery and has now been ruled out of Saturday's game against Championship leaders Southampton.
