Valencia having knee surgery, out 6-to-12 months

Newly acquired Portland Timbers forward Jose Adolfo Valencia

will be sidelined for 6-to-12 months following knee surgery.

Valencia, son of former Colombia national team star Adolfo

Valencia, had damaged cartilage in his left knee repaired Monday by

team director of medicine Dr. Jonathan E. Greenleaf.

The Timbers said Friday it was uncertain when Valencia was hurt

and said they amended the original terms of the loan agreement

reached in December with Colombia’s Independiente Santa Fe. Under

the reworked deal, he will not count as a young designated

player.

He will rehabilitate in Portland while on the Timbers’ disabled

list.
