Swinton Lions have confirmed forward Jose Kenga suffered a ruptured Achilles during their win over Bradford Bulls on Saturday.
Kenga was forced off less than two minutes after coming on, during the 26-22 win in Dewsbury.
The Lions have confirmed he could be out for several months, while he recovers.
Head Coach Stuart Littler told the club website: “Sadly it’s not great news from the hospital regarding the injury to Jose. There is always a risk in any rugby match of a player getting injured due to contact and the physical elements of the game. But to be fair in this case, having looked back at the video, it’s hard to determine what actually went wrong.
“We have been in constant contact with Jose since last Saturday and we have already started to formulate a rehab programme to get him back up and running. Jose will now focus on getting his recovery right with our medical team who have been outstanding throughout pre-season.
“Things are sometimes sent to test us. But by focussing on the positives it allows us to build resilience to adversity in challenging times. We are a close team and we will all support Jose to get back on that field as soon as possible.”
