Barcelona Captain, Lionel Messi was excused from training on Monday, raising fears he may miss the Copa del Rey semifinal-first leg against Real Madrid on Wednesday.
Messi injured his thigh in Saturday’s 2-2 draw against Valencia but was able to finish the game.
Barca coach Ernesto Valverde has however played down fears over the injury after the match.
Sources however revealed that the 31-year-old still had pain in his thigh when he arrived at the training ground on Monday, and will undergo tests to determine the extent of the problem.
Valverde is unlikely to take any risks with Messi as Barca prepare for an intense run of games this month.
They face Madrid before travelling to Athletic Bilbao on Sunday, with Real Valladolid then due at Camp Nou before trips to Lyon in the Champions League and Sevilla in La Liga and back-to-back games at the Bernabeu in the Copa del Rey and the league.
Messi missed the first Clasico of the season with an elbow injury, but that did not stop Barca from beating Madrid 5-1. They also defeated Inter Milan in the Champions League without him.
