Barcelona defender Javier Mascherano has suffered an injury to his left thigh, the LaLiga champions have confirmed.
Mascherano was introduced as a 62nd-minute substitute in place of Denis Suarez during Tuesday's hard-fought 1-1 draw against Atletico Madrid in the Copa del Rey.
"The FC Barcelona medical staff have confirmed after tests carried out on Javier Mascherano that the first team player has a left thigh injury," a club statement read. "His return to action will depend on his recovery."
Although Barcelona did not put a timescale on Mascherano's recovery, a report by Mundo Deportivo said he could face two to three weeks on the sidelines – an absence that would rule him out of next Tuesday's Champions League last-16 trip to Paris Saint-Germain.
