Barcelona, in a statement on their website, reported: "After training with the rest of the team on Saturday Leo Messi will be included in the squad against Betis."
The league leaders go to Seville looking to defend a six-point advantage over Atletico Madrid and 11 over Real Madrid at the scene of the latter's latest upset a fortnight ago. Messi came on in the 58th minute of Wednesday's tie only to collide with Benfica goalkeeper Artur Moraes six minutes from time.
The sight of their star player being stretchered off the pitch silenced the Barca fans, but there was relief soon after with the club confirming the injury was no worse than a bruised left knee.
