Adam Chapman and Jake Wright come into the starting line-up as Oxford United attempt to end Shrewsbury Town’s 24-game unbeaten run at home.

Chapman replaces the injured Mark Wilson for his first U’s start since the play-off final at Wembley in May 2010.

Wright missed Saturday’s 2-0 win against Swindon Town with a back injury, but the skipper returns well ahead of schedule.

Top scorer James Constable starts his three-game suspension, so Oxford boss Chris Wilder switches from 4-4-2 to 4-3-3, with Andy Whing pushed forward from centre-half into midfield.

Teenage striker Tyrone Marsh is among the substitutes and would make a first-team debut if he comes on.

Shrewsbury start the evening fourth in the npower League Two table but will return to the automatic promotion places with a victory.

Oxford (4-3-3): Clarke, Batt, Duberry, Wright, Tonkin, Chapman, Hall, Whing, Johnson, Rendell, Holmes

Substitutes: Brown, Worley, Davis, Marsh, Kerrouche
