Cramb joins the Mariners after he was released from Shrewsbury last week. At Gay Meadow his attitude was questioned by manager Jimmy Quinn.
Cramb brings a colourful history to Blundell Park with him. At Crewe he was kicked out after a training ground scrap with midfielder Lee Bell. Whilst in Holland he insulted a referee so much during a game that the official walked off the pitch.
Russell Slade will be hoping that Cramb has put his badboy days behind him though as he looks to add something different to his frontline.
With Darren Mansaram out on loan, Slade is without a centre forward of sorts and he will no doubt see Cramb as filling that void.
