Matt Prior said: “Today is a very sad day for me as I am forced to announce my retirement from the game I love. I had been hoping and expecting to be fit for the start of the 2015 season. Unfortunately, this has proved impossible, and I have now had to reach this decision.” Thanks for all your support over the years guys. See you all soon https://t.co/VtwtxDcZd9 – Matt Prior (@MattPrior13) June 11, 2015 One of the most prolific wicketkeeper-batsmen in the history of the international game, Prior played the last of his 79 Tests for England in last summer’s Test Match against India at Lord’s and he leaves the international stage with 4,099 Test runs and 256 Test dismissals to his name. His career tally with the gloves leaves him behind only Alan Knott in the list of England wicket-keepers in Test cricket, ninth in the all-time world list, and he also claimed a further 88 dismissals in one-day and T20 international cricket. Congrats @MattPrior13 on a brilliant Eng career….
