Captain Cabango among injury concerns for Swansea

Ben Cabango replaced Matt Grimes as Swansea's club captain last season

Swansea City are assessing Ben Cabango's fitness with the Wales centre-back among a number of defensive injury concerns for Alan Sheehan.

Swansea captain Cabango, 25, missed the friendly win over Stevenage in Spain last weekend after picking up a problem during the club's pre-season training camp.

Cabango was again missing on Wednesday as Swansea were beaten 2-1 in another pre-season fixture by League Two side Cheltenham Town.

"Ben just felt something," head coach Sheehan said.

"We want to look further into that without risking him in the next few days."

There was further bad news at Cheltenham as summer signing Ricardo Santos was forced off in the first half.

"He landed really funnily. We will have to assess that and see how he is," Sheehan told Swansea's website.

"[There have been] quite a few little things really that are freakish and unfortunate at the moment.

"It's about not risking anybody at the moment so get him (Santos) off and assess him straight away."

With academy product Filip Lissah nursing an ankle problem suffered during pre-season, Cameron Burgess is Swansea's only fit senior central defender with their Championship opener at Middlesbrough only 16 days away.

Swansea lost defensive regular Harry Darling to Norwich City this summer, while Hannes Delcroix returned to Burnley after a loan spell and Cyrus Christie, Kyle Naughton and Kristian Pedersen were released.

Attacking midfielder Eom Ji-Sung, meanwhile, is due back in training on Thursday having missed the Spanish trip with what Sheehan called "a little twist of the ankle".

Florian Bianchini is another player who was absent at Cheltenham.

Sheehan revealed Swansea will meet Barnsley in a behind-closed-doors game on Friday before they play another pre-season friendly at Exeter City on Saturday.
