Montevideo: Uruguay international winger Cristian Rodriguez faces a race against time to be fit for Penarol's decisive clash with Progreso in the Uruguayan top division on Sunday.
The 33-year-old former Paris Saint-Germain and Porto player suffered a calf injury in his team's 1-1 draw with rivals Nacional on Saturday, reports Xinhua news agency.
He missed training on Monday and will be assessed later in the week before a decision is made on his availability, according to club officials.
Penarol will secure the Clausura title -- one of Uruguayan football's three annual top flight competitions -- if they beat 10th placed Progreso at home on Sunday.
