Trio released by Yorkshire
Ashraf, a right-arm seamer, leaves the club after five years in which he made 21 First-class appearances taking 43 wickets.
The 23-year-old’s best season came in 2012 when he spearheaded Yorkshire’s T20 attack with Australian international Mitchell Starc, helping the White Rose County reach finals day at Cardiff losing out to Hampshire in the final.
Wicketkeeper batsman Hodgson, a product of the successful Leeds Bradford MCCU set-up, joined Yorkshire in 2012 and has been a mainstay of Yorkshire’s Second XI this season, captaining the side on a number of occasions.
He played a major part in the club’s 2012 Champions League appearance in South Africa, where he kept wicket in the absence of senior players Jonny Bairstow and Andrew Hodd.
Last season he spent some time on loan at Derbyshire.
Former England under-19s batsman Tattersall has made one List A appearance for the club during the 2013 season against Glamorgan at Headingley.
He is renowned for his excellent ability as a fielder and has substituted for the England senior side on a number of occasions.
The Knaresborough born right-hander’s career highlight came in 2014 when he represented England under-19s at the ICC World Cup in the UAE where he helped his country reach the semi-finals.
Yorkshire’s Director of Cricket Martyn Moxon, said: “While I have expressed our gratitude for each individual, collectively I’d like to thank each of the players for their commitment to the club and wish them well.
“We will always welcome them back in the future.”
