Raven has not played since the 4-2 win over Macclesfield in the Johnstone's Paint Trophy on October 6 because of a hip injury and he will be assessed ahead of the game.
Regardless of Raven's fitness, manager Greg Abbott may again opt to field a reshuffled back four against Phil Parkinson's men.
Ian Harte has been switched from the left-back slot to play at centre-half, while Richard Keogh has moved from the middle to play at right-back, with Evan Horwood playing on the left.
The move proved successful as United ended a seven-game winless run against Southend last weekend and Abbott could go with the same style against the Addicks.
Striker Richard Offiong (hamstring) is a doubt for the Cumbrians, while skipper Paul Thirlwell (Achilles) and teenager Simon Lakeland (knee) are out.
