LAST TIME AT BRISBANE ROAD: Leyton Orient 2 Bristol Rovers 3 (League Two 03-09-05)

HEAD-TO-HEAD: Orient 32 wins, Bristol Rovers 41 wins and 26 draws. The last time the two sides met in the FA Cup was in a fourth round tie in 1999, when Rovers secured a 3-0 home win. The O's also lost out 1-0 to the Gas in the competition in 1952 after the original tie had finished 1-1 at Brisbane Road, although prior to that the east Londoners secured a 1-0 FA Cup win in 1930.

FORM: Since Orient beat Rovers 3-2 at the Memorial Ground at the end of September, Rovers drew three straight games in the league followed by two defeats. This included a 2-0 home defeat against Bournemouth on Saturday, before they won 1-0 at Northampton on Tuesday night.

DANGER MAN: Striker Richard Walker (below) who looked to have given his side victory over the O's in September with two penalties that put them 2-0 up before the Londoners late comeback, has scored four goals in total this season.

FUN FACT: While Rovers have lacked a bit of punch this season, listed amongst their famous fans are boxers Glen Catley and women's fighter Jane Couch (above). Bristol-born boxer Couch is arguably one of the most recognisable faces in the women's game after first stepping into the ring in 1994.
