Beevers missing for Saddlers
Walsall will be without Lee Beevers for their crunch trip to Exeter but manager Dean Smith is boosted by the return of Richard Taundry.
Right-back Beevers was shown red for a second bookable offence during injury time in last weekend's disappointing 1-0 home defeat to Tranmere, resulting in a one-match suspension at St James' Park.
But Taundry, who missed the clash due to a recurrence of his troublesome hamstring strain, played an hour for the club's reserves in midweek and will be in contention, along with Darryl Westlake, to replace Beevers.
Midfielder Peterlin also returns to the fold after an ankle injury having played the full 90 minutes for the second string.
Striker Will Grigg pushed his claims for involvement against the Grecians by bagging four goals in the reserves' 6-3 win over Burton.
Victory for the Saddlers would relegate Exeter and potentially go a long way to securing their own League One future, with fourth-bottom Wycombe away to runaway leaders Charlton.
