Scarlets will be without fly-half Steven Shingler for a further ten weeks after the Welsh region issued an update on his knee problem.
The playmaker, who initially suffered the injury against Edinburgh in February, is now set for an extended spell on the PRO12 sidelines.
In other injury news from the camp ahead of Friday's clash with Treviso at Parc y Scarlets, hooker Emyr Phillips is out for the season.
"Hooker Phillips suffered knee ligament damage in the New Year's Day clash against Cardiff Blues at BT Sport Cardiff Arms Park. He underwent surgery to repair a ruptured anterior cruciate ligament on Wednesday 6th January and has been ruled out for the reminder of the season," read a statement that included several other concerns in the squad.
"Back-row prospect Jack Condy suffered a shoulder injury in the region's defeat to Cardiff Blues on New Year's Day. He underwent surgery on Friday 8th January and was expected to be out for up to ten weeks.
"Number eight Morgan Allen suffered a foot injury in Sunday's defeat to Edinburgh and is expected to be out for a few weeks."
Also unavailable for this game is George Earle, who suffered a shoulder injury against Edinburgh last Sunday, with the update continuing: "Rory Pitman will undergo a scan this week on a pectoral injury suffered in Sunday's PRO12 clash against Edinburgh."
"Flanker Lewis Rawlins is unavailable for selection having suffered a shoulder injury in the defeat to Connacht at the end of January.
"Flanker Aaron Shingler is following return to play protocols having suffered concussion in the victory over Ulster at Kingspan Stadium in February.
"Scrum-half Rhodri Williams is following return to play protocols having suffered concussion in Sunday's PRO12 clash against Edinburgh."
On a positive note, however, Scarlets do welcome back Jake Ball and Aled Davies from Wales' Six Nations camp as well as John Barclay from Scotland for this week's PRO12 clash.
