Crawley will be without Joe Walsh and have doubts over three players for the Johnstone's Paint Trophy visit of Newport.
Walsh is on international duty with Wales Under-21s and fellow defender Kyle McFadzean is struggling with flu.
Midfielder Mike Jones is a doubt with a rib injury and striker Billy Clarke is carrying a knee knock.
Mark Connolly and Connor Essam could be drafted in at the back while Gary Alexander is pushing for a start in attack having returned from a three-match ban as a substitute at Sheffield United on Friday.
Newport manager Justin Edinburgh will be without the suspended Harry Worley.
The defender picked up his fifth yellow card of the season in the goalless draw at Bury. Billy Jones is in line to replace him.
Edinburgh could not fill his substitutes' bench again at the weekend. Ryan Burge and Aaron O'Connor are expected to be among the absentees as the Exiles, given a bye into the second round, make their first appearance in this season's Johnstone's Paint Trophy.
Newport have not featured in the competition since 1987-88, when they fell in the second round to Hereford.
