After going down in the 26th minute of Saturday's season finale, it appears that Diego Valeri may have suffered a torn ACL, according to a report by the Oregonian's Jamie Goldberg.
Valeri has undergone an MRI and will receive more testing today.
A torn ACL could keep Valeri, the 2014 Supporters Player of the Year and a 2014 MLS All-Star, out of the first team for around six months and would cause him to miss the start of the 2015 season.
The Timbers are all too familiar with players getting injured late in the season and missing time early on. Valeri spent most of the 2013-14 offseason recovering from surgery to correct a sports hernia surgery and, while he was back with the team at the start of the year, it took Valeri some time to get back up to full speed.
Last year Rodney Wallace also suffered a torn ACL in the final match of the season: the Timbers' second leg of their playoff series against Real Salt Lake. Although Wallace was a force for the Timbers late in the season this year, he did not play his first game of 2014 with the Timbers until June 27th.
After 2014's slow start, this injury is especially worrisome as the Timbers may be forced to start 2015 without both Valeri and Will Johnson, who is recovering from a broken tibia and fibula, suffered last month.
