WEDNESDAY stars Francis Jeffers and Frankie Simek are to speed up their comebacks with a week's intensive work at Lilleshall.
The pair will head for the National Rehabilitation Centre instead of joining the Owls' trip to Holland next week.
Manager Brian Laws explained: "This is just to speed them up ... they're not quite ready for contact play yet.
"Hopefully when we get back from Holland they'll be close to getting games.
"Frankie is slightly behind Franny at this stage. But they are both making great progress."
Both players are on the way back from serious ankle injuries.
Jeffers was hurt by a bad tackle at Stoke last October and made a brief comeback at the turn of the year but needed a further lay-off and treatment.
Simek has not played for the first team since damaging his ankle when he landed awkwardly on it at Crystal Palace in December.
Laws hopes to have a fully fit squad for the start of the league season. Akpo Sodje, Marcus Tudgay, Wade Small and Richard Hinds are all back in training - they missed last season's run-in because of injuries.
The Owls leave on Sunday for a five-day stay in Holland.
They play Haarlem on Tuesday and Stormvogels Telstar on Thursday. Both games take place in the town of Heiloo.
The club's first friendly back in this country will be at Mk Dons on July 22.
Other games are at Stocksbridge on July 23, Bury on July 26, Chesterfield on July 29 and Sheffield FC on July 30.
The friendly programme ends with a Hillsborough game against Wigan on August 2, a week before the league campaign begins with a home game against Burnley.
Laws was today set to carry out his parachute jump to raise money for Sheffield Children's Hospital medical research campaign.
Laws' leap takes place at Hibaldstow Airfield near Brigg, Lincolnshire.
