MONTEVIDEO, Oct. 22 (Xinhua) -- 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.

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.

The Montevideo outfit are currently four points ahead of second-placed Nacional with two rounds remaining.
