Udinese star Alexis Sanchez picked up an injury in training on Tuesday and is a doubt to play against Roma at the weekend.
The 22-year-old Chile international has been an absolute revelation this season. He has scored 12 goals in 28 games in Serie A alongside Antonio Di Natale.
La Gazzetta dello Sport understands Sanchez felt a pain in his left leg and underwent a scan to determine if he had torn a muscle.
Fortunately, such an eventuality was ruled out, but the latest reports claim he is still unlikely to feature when Udinese host Roma on Saturday.
Udinese lost for the first time in 2011 last weekend, suffering an unexpected 2-0 defeat to relegation threatened Lecce.
Francesco Guidolin's side remain in fourth place, but still have to play Napoli, Fiorentina, Lazio and Milan.
