Jeremain Lens was axed from Sunderland’s first-team squad and is set to be fined two weeks' wages after refusing to take part in a post-match workout, Sportsmail can reveal. The Holland forward – a £9million summer signing from Dynamo Kiev - was an unused substitute during the 1-0 home defeat to Watford last weekend. Afterwards, Lens infuriated manager Sam Allardyce and his backroom team by refusing to join his fellow subs in a running exercise on the pitch at the Stadium of Light. The Black Cats boss and the club are now in the process of imposing a maximum fine – thought to be in the region of £100,000 – and Lens trained with the Under-21s towards the end of last week.Jeremain Lens failed to take part in running exercise after Watford defeatDutchman set to be handed maximum club fine and trained with Under 21sDropped for Sunderland's squad against Chelsea for 'disciplinary reasons'Boss Sam Allardyce and players infuriated by forward's attitude

Over 430 professors, assistants and faculty have left the University of Simon Bolivar, in Caracas, since 2015, according to Azzato, the university's vice rector of administration. The public university is widely considered one of Venezuela's best, yet more than a third of the faculty have left in three years.
