Raphael Rossi Branco is in danger of missing the visit of Wigan Athletic to The County Ground on Good Friday after succumbing to yet another injury.
The towering centre-back missed the 0-0 draw away at Coventry City on Saturday after sustaining a calf problem in the week leading up to the game.
Branco – who has one goal in 32 appearances for the Robins so far this term – has been hampered by a string of knocks since mid-February and has now missed four of Town’s last five outings.
And the former Brighton and Hove Albion man now faces a race against time to prove his fitness in time for Friday’s clash against the Latics, although the injury is not thought to be too serious.
“We thought that Raphael had cramped up in the calf in the Millwall game, but it turns out that it was a little bit more serious than that,” Town Head Coach Luke Williams told BBC Wiltshire.
“I don’t think it is anything that is going to keep him sidelined for a great deal of time, but he certainly wasn’t able to be risked (on Saturday).
“We’re fortunate that we’ve got Jamie (Sendles-White) who can step in and I think it is fair to say that he was excellent (against Coventry).”
Both Nathan and Louis Thompson were suffering with illness at the weekend and were both sick during half-time but opted to play on and lasted the distance, earning praise from their boss.
“Both the Thompson brothers were sick at half-time and people are probably sick of me talking about the Thompson boys, but it is hard not to when you are a manager or a head coach at a football club and you’ve got these two boys that are prepared to give everything,” he continued.
“It’s the one thing that every coach dreams of having that type of character.
“Both boys were sick a couple of times in the interval and at no point suggested that they needed to come off.
“It didn’t appear to affect their performance in any way.
“Whatever it was it seemed to be a short-term thing and they seem to be fine – it didn’t have any lasting effects.”
Meanwhile, Lawrence Vigouroux could return to the fold against Wigan Athletic after a dead leg ruled him out of the draw with Coventry City.
