The U's conceded late goals to draw 1-1 with Morecambe on Good Friday and then to lose 3-2 at Aldershot on Easter Monday, results which all but ended their hopes of gatecrashing the play-offs.
And they will be without Raynes who picked up two yellow cards in that loss to the struggling Shots.
Manager Chris Wilder looks set to be without winger Sean Rigg as well. The former Bristol Rovers man limped off in the opening 10 minutes with an ankle injury which the club are assessing this week.
Jon-Paul Pittman will hope to keep his place in the side after marking his first appearance since suffering a dislocated shoulder at Accrington on December 1 with a goal on Monday.
