Today Rovers signed midfielder Ed Upson from MK Dons, so we've taken a look into the the 28-year old's background.
Ed spent his youth career at Ipswich Town, signing a professional deal at the age of 17 before going on two brief loan spells at Stevenage and Barnet respectively.
In 2010 after making two League Cup appearances with Ipswich, Ed made a permanent switch to then League One side Yeovil Town, where he enjoyed three campaigns in the third tier with the latter resulting in promotion to the Championship via the Play-offs.
The Glovers however only survived one season in the Championship, but Ed proved his quality at the level and as such was snapped up by Millwall in the January transfer window, avoiding the drop with Yeovil and continuing in the division.
His first full season with The Lions followed in similar fashion to his last with Yeovil, however this time the midfielder stayed the whole season and dropped down to League One with Millwall.
The former England Under-19 international remained for one more season in the third tier with Millwall, before making a switch to his most recent club MK Dons in the same league.
Ed was a mainstay in the Dons side for his two seasons at the club, making 93 appearances and scoring seven goals before switching to the Gas for the next chapter of his career.
