Barcelona Defender Mathieu out due to calf injury

The 32-year-old has damaged a muscle in his right leg and
has been ruled out of Sunday's Liga clash with Athletic
Bilbao at Camp Nou, the club have confirmed.

"The development of the injury will determine his availability
for the coming matches," a Barca statement added.

Mathieu's injury comes at the beginning of a run of five
matches in just 13 days for Luis Enrique's side.

Following Sunday's game, they travel to take on Athletic
once again in the first leg of their Copa del Rey quarter-final
tie on Wednesday before a trip to Malaga just three days
later.

Barca then face Athletic in the second leg prior to a pivotal
clash at Camp Nou on January 30 against title rivals and
current Liga leaders Atletico Madrid.
