After tearing his ACL in the Portland Timbers' final game of the 2014 season, Diego Valeri has undergone surgery at the Oregon Outpatient Surgery Center. According to the team, the surgery was successful.

The estimate that Valeri will be out for approximately five months remains the same. Last season, Rodney Wallace was estimated to need five to seven months to make his return after suffering a similar, but slighly worse, injury and was back on the field with Arizona United in six months and with the Timbers in seven.

The five month time-frame would put Valeri back with the Timbers early in the season, potentially in April.

Dr. Richard Edelson, who operated on Valeri, has seen a number of Timbers players over the last four years including Wallace, Bright Dike, Mikael Silvestre, and Brent Richards.

The surgery means that, for the second straight year, Valeri will spend his offseason rehabbing from surgery with the Timbers training staff.
