Marco Melandri has made a tentative return to training following surgery on his shoulder, though his arm remains in a brace for the time being.
The Italian went under the knife during the Christmas period to 'clean up' the limb after complaining of a pain in his shoulder in recent weeks.
Though there are concerns he will not be fit in time for the upcoming official pre-season test at Portimao, Melandri has kept his fans notified of his progress on Twitter
, posting a photograph of him training on a static bike.
The image also shows his arm still in a brace following the surgery, though he says this will be taken off in the next few days, his most recent message stating 'Did some therapy but still I can not move my arm till friday, 3 days delay but keep pushing…'
Having tested the Yamaha R1 at Valencia and Phillip Island, the Portimao test will be the first time the MotoGP race winner has squared up to the majority of his WSBK competition.
