The 28-year-old replaced Dean Lyness in the Brewers' starting line up on Saturday on his return from a three-month absence with a knee injury.
Tomlinson kept a clean sheet and was singled out for praise by manager Gary Rowett as Burton beat Barnet 1-0 to record a fifth success home league win.
Ian Sharps also caught Rowett's eye on his debut after arriving on loan from Rotherham and the experienced centre-half should also keep his place against the U's.
Rowett has defenders Aaron Webster and Nathan Stanton, midfielders John McGrath, Jimmy Phillips and Jack Dyer and striker Matt Paterson available should he wish to make changes elsewhere.
Burton striker Justin Richards is on loan at Oxford and is not allowed to feature against his parent club.
