Exeter Saracens will hope last Saturday's second XV game against OPM turns out to be a dress rehearsal for this week's first meeting between the two sides.
OPM are bouncing around in the bottom three and a win over them will hoist Sarries comfortably into mid-table.
Sarries, who didn't have a game in the Cornwall & Devon Division last weekend, beat OPM's seconds 60-12.
Player-coach Rob Hilton, who watched the game, said: "A young second team recorded a convincing win with some very strong performances from some individuals who will be pushing for first team selection this week.
"We hope to put out a strong side to face OPM on Saturday in what we consider to be a very important match."
Players coming back from injury and available for selection include Sarries skipper Matt Hilton, Ross Watts, Scott Diack and Steve Kirk.Withycombe will travel to winless South Molton without Lee Tainton.
The young half-back was helped off with a dislocated shoulder during his side's 14-5 Devon Intermediate Cup loss at Teignmouth last weekend.
Tainton was patched up at the Royal Devon & Exeter Hospital and sent home that night.
He is due to have a follow-up appointment this Thursday to asses the damage was done.
Nigel Symons, Withycombe's director of rugby and Tainton's step-father, said he is unlikely to play again for the next two months.
Withycombe's lone try in the cup was scored by lock Tim Wills.
Second-placed Crediton can expect a stiff test of their promotion credentials when they visit Paignton this Saturday.
Tiverton, from the division above, only just scraped home 19-17 in the cup at Paignton last time out while Crediton were winning 22-13 at Bodmin.
That win at Bodmin put Crediton level at the top with Saltash and Withycombe. Points difference is all that separates them.
Bernie Blatchford, the coaching co-ordinator at Blagdon, said he saw it staying tight for the rest of the season, meaning there are some huge games coming up.
"We're all level and it looks like a three or four-horse race," said Blatchford.
"We haven't all played each other yet, we've got Paignton then Pirates Amateurs so after the next two games we'll have a fairly rough idea of where we are.
"Then it could come down to when we all play each other in the second half of the season."
The win at Bodmin was achieved with a number of players missing, showing the strength in depth at Crediton.
"We had a lot of changes, we were missing five or six first-choice players for whatever reason," said Blatchford.
"The young lads who came in did okay and it was a good experience for them, but we were a bit disappointed with our performance."
Crediton led 12-6 at half-time against Bodmin, with Tom Ronchetti converting his own try and Bobby Mogford also dotting down.
They pulled away in the second half as veteran prop Wayne Reed scored twice.
Kirton could be back to full strength this weekend, with Josh Lee the main doubt after injuring an Achilles in October.Honiton are at home to Hayle having had a week off to get over a clutch of injury problems.
The Lacemen have lost three on the trot and four of the last five, dropping them down to eighth.
"We hope to get a stronger side out than the one we took to Falmouth and lost with," said Allhallows assistant coach Jerry Rice.
