The world number one had tests on the injury, which wrecked
his chances in Sunday's Australian Open final, in Barcelona on
Tuesday followed by the treatment before returning to his native
Mallorca to rest, the spokesman said in an emailed statement.
"Next Monday he will have further tests to evaluate the progress
of his recovery and to see if he can gradually start training
again," he added.
Nadal still intends to play in the clay event in Buenos Aires
starting on February 10, followed by the tournament in Rio de
Janeiro, also on clay, and the hard court Masters events at
Indian Wells and Miami.
Nadal lost to Swiss Stanislas Wawrinka in the Australian Open
final, which prevented him drawing level on 14 grand slam
singles titles with American Pete Sampras, three short of record
holder and great rival Roger Federer.
He needed lengthy treatment at the start of the second set, hit
back to win the third but Wawrinka eventually captured his debut
slam with a 6-3 6-2 3-6 6-3 triumph.
