Barcelona star Lionel Messi in light training after injury scare
'Leo Messi who played last night worked out in the weight room today,' read a club statement on their website as fears about the seriousness of the Argentine's injuries began to wane.
"Messi was the victim of a bruise on the outside of his knee and will undergo further tests to determine the exact damage," said the club.
Messi came on in the 58th minute against Benfica in a match that was meaningless to Barcelona but was chasing his 85th goal of the calendar year which would have equalled Gerd Mueller's long-standing record.
Early reports said the 25-year-old may be out of action for two weeks.
Barcelona have three Liga matches before the end of the year, including a top of the table clash at home to Atletico Madrid on December 16, before their final match of the year on December 22 when they travel to Valladolid.
