Bulls boosted by duo

Defender Luke Graham and midfielder Josh O'Keefe are again expected to feature in Hereford's squad for the FA Cup derby against Shrewsbury.
Graham (hamstring) and O'Keefe (knock) were involved against Southport last week and should again feature in Martin Foyle's plans.
However, Foyle still has plenty of injuries to concern him, with striker Marlon Jackson still out with a torn hamstring and wing-back Chris Carruthers continuing to struggle with an Achilles injury.
Winger Marley Watkins (knock) is also still doubtful but Foyle will be relieved that all three of his loanees, strikers Kyle Perry and Phil Marsh and defender Chris Todd, have been given permission to play in this game.
Hereford have only won twice in their last 10 matches and the club are currently involved in a cost-cutting exercise to avoid going into administration.
Marvin Morgan makes a welcome return for Shrewsbury.
Morgan is Town's leading marksman this season having bagged five goals, however he has missed the club's last two games through suspension following his sending-off at Portsmouth, but is back in the fold at Edgar Street.
Midfielder Asa Hall is likely to start having stepped off the bench last weekend to score two headers in the space of three minutes and secure a 2-2 draw against Colchester.
Loanees Lee Collins, Jeremy Helan and Jamie Proctor have each been given permission to play by their respective parent clubs.
The clash, which kicks off at 1pm, sees Shrews boss Graham Turner return to the club where he spent a total of 15 years between 1995 and 2010 during spells as manager, chairman and even majority shareholder.
