Multiple team sources have told CSNNW.com that Oregon junior wide receiver Bralon Addison tore the anterior cruciate ligament in his knee while performing a non-contact drill during Wednesday's practice.

Such injuries can take up to nine months to recover from, which means Addison, the team's top returning receiver, will likely miss the entire 2014 season.

Addison was second on the team last year with 890 receiving yards, and he scored seven receiving touchdowns. He was set to become the team's top target after the departure of senior Josh Huff for the NFL.

Addison also led the team in punt return yards last season.

Should Addison be lost for the season, senior Keanon Lowe would become the team's top returning wide receiver. He had 233 yards receiving and three touchdowns last season.
