Mariga was forced off the encounter at the Stadio Tardini on Sunday after only five minutes in a game that eventually ended goalless.
Now Parma have confirmed in their official website that the utility player they acquired on loan from former European champions Inter Milan, will be out of action for three weeks.
“Mariga has been ruled out of action for three weeks because tests have diagnosed that he has a lesion of the left thigh 'adductor miotendinea'. The prognosis is about 20-25 days.”
After sustaining the injury, Mariga had revealed to Goal.com that they injury was not that ‘serious.'
"I felt sharp pain that persisted. Its nothing serious, The injury will be assessed by the medical team, but am certain to be available for the next game."
Mariga moved to Parma from parent club Inter Milan in a temporary arrangement during the January transfer window after guarantees from boss Roberto Donadoni that he will get more first team appearances.
News of the latest setback by the player will also be received with interest by Harambee Stars technical bench, as coach James Nandwa had revealed that his intentions to use the former Helsinborgs player during the upcoming World Cup qualifier against Nigeria in March.
Mariga only returned to fitness last November after a seven months layoff since picking a knee injury on in Serie A game for Parma against Novara.
