Liverpool FC goalkeeper Pepe Reina is a fitness doubt for the Premier League clash with Reading after picking up a hamstring injury while on international duty.

The Reds keeper was an unused substitute during Spain’s 1-1 draw in Madrid last night against France, but complained of discomfort after taking part in a half time warm up.

Reina told reporters, “The injury is not serious. I got injured at half time. I will do more tests at Liverpool.”

The extent of the injury is still yet to be confirmed, but should become clearer when Reina returns to Liverpool’s training ground Melwood and checked out by the club's medical teams.

If the 30-year-old goalkeeper can not recover in time for the visit of newly promoted Reading, then it will hand Brad Jones his first Premier League start for the club.

The Australian keeper’s only other appearance for Liverpool  came back in April when he came off the bench against Blackburn following the dismissal of Alexander Doni.

Reina has only missed four games for Liverpool since May 2007, with a run out of the team being enforced on him toward the end of last season due to suspension.

Losing Reina to injury would be a major blow for struggling boss Brendan Rodgers, who has also seen striker Fabio Borini sidelined with a broken foot during the his time with Italy.

The international break has not given Rodgers any respite, seeing some key players pick up injuries, one bit of good news is that striker Luis Suarez will come back to Merseyside unscathed following Uruguay’s 4-1 defeat against Bolivia last night.
