Rothes have placed their leading scorer Joao Rodrigues on the transfer list
Portuguese-born Rodrigues, 25, has scored six goals for the club this season but has slipped down the pecking order at Mackessack Park.
The Speysiders, who travel to Deveronvale today, will include defender Gary Lamberton, brother of co-manager Paul, as a trialist.
Vale will miss suspended defenders Liam Forbes and Kyle Rae but midfielder Craig Cowie returns after suspension and Michele Lombardi is available. Stuart Leslie is offshore.
Inverurie Locos will look to consolidate fourth spot in the table when they travel to take on a Forres Mechanics side looking to end a three-game losing streak.
Locos co-manager Kenny Coull said: “We certainly won’t be taking anything for granted tomorrow as they are a big, strong side. We need to keep our standards up after last week’s excellent 2-0 home win over a very good Clach team. We will be without Marc Young, who is suspended after getting sent off last weekend.”
Can-Cans manager Charlie Rowley said: “We need to show great improvement. We have the squad to compete with them.”
Lossiemouth and Cove Rangers meet at Grant Park. The Coasters are without experienced centre forward Shawn Scott, who has a broken toe, and defender Greig Watson, who has a knee injury.
Cove welcome back attacker Daryl Nicol from holiday in Australia but full back Dean Lawrie is doubtful with a groin strain. Goalkeeper Sandy Wood is unavailable, so Murray Kinnaird is set to deputise.
