Derby's Nathan Tyson suffers fresh groin injury blow
Derby County striker Nathan Tyson could be sidelined until the middle of November after another injury setback, reports BBC Radio Derby.
Tyson was due to play in a friendly against Chesterfield on Wednesday but had to pull out with a groin injury.
It is thought the latest problem is different to the groin injury Tyson suffered in pre-season.
Leading goalscorer Steve Davies was earlier this week ruled out until January with a fractured skull.
Tyson 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.
