Westley`s men won 1-0 at Crewe on Saturday and the only change to their starting line-up saw Luke Foster take Bostwick`s place in defence.
Bostwick missed out due to a virus and is still suffering, so Westley is likely to name the same starting line-up.
Midfielder Darren Murphy is a definite absentee as he works his way back from an ongoing shoulder problem.
Scott Laird snatched all three points for Stevenage with a late winner at Gresty Road and Westley was full of praise for his men.
He said: "It was a classic away performance and a very important three points."
