Will Spencer, Jonny Arr, Wynand Olivier and Chris Pennell in contention for Worcester Warriors' clash with Saracens

Centre Wynand Olivier and scrum-half Jonny Arr have also returned to training while fit-again full-back Chris Pennell is pushing for a starting spot.

Spencer has not played since injuring his ankle in Warriors’ season opening 35-8 defeat at Newcastle Falcons earlier this month.

Former South Africa international Wynand Olivier has recovered from a hamstring problem which he sustained in the warm-up at Kingston Park.

With influential number nine Francois Hougaard (hip and groin) out, director of rugby Gary Gold will be delighted to have Arr available.

The 28-year-old is “symptom free” after suffering a bang to the head in Warriors’ heavy beating by Exeter Chiefs two weeks ago.

Gold may also be tempted to call upon the experienced Pennell who played 56 minutes of Worcester Cavaliers’ loss to Northampton Wanderers on Monday.

“Will has trained this week which is good for us,” Gold said.

“He is obviously a stalwart of the pack and it will be really good to have him back.

“Jonny is symptom-free so he has been training, Chris played on Monday night and Wynand is training and is available for selection as well.”

Flanker Sam Lewis (neck) and second row Pierce Phillips (dead leg) face a race to be fit after picking up knocks in last Friday’s 24-19 defeat at Gloucester.

But Gold will be without Ryan Mills who has been hit with a quad injury just days after overcoming hip and shoulder issues.

With Tom Heathcote sidelined with concussion, versatile back Jamie Shillcock appears to be in prime position to claim the number 10 jersey.

The other option for Gold is Olver who completed the full 80 minutes of Cavaliers’ match against Northampton.

“It is tough times at the moment, primarily not because we are not winning but because we are picking up these injuries,” Gold added.

“It goes that like. It is like London buses as they all arrive at the same time.”
