Roe, 19 has worked his way through the academy and is tipped to be a good prospect in the next few years.
He has yet to feature in the first team but was an unused substitute in the Blades 2-0 defeat at Hartlepool United in the League Cup earlier this season.
However he has featured heavily in the reserves and played in the 1-0 victory over Sheffield Wednesday Reserves recently at Bramall Lane.
Roe made his Badgers debut (along with Paul Shaw) in this weekend's 2-1 defeat at Ossett Town.
