Oregon State junior wide receiver Seth Collins is out indefinitely with an unspecified "health-related issue," the school announced Tuesday.

Collins missed the Beavers' game Saturday against Colorado due to an illness. He greeted teammates as they got off the bus at Reser Stadium prior to kickoff but was not on the sidelines for the game. Collins, a 6-foot-3 slot receiver, was also not at practice Tuesday.

OSU said the health issue is not related to the illness that kept Collins out for the final two games last season, as well as spring practice. Collins said during fall camp he had been on his "deathbed."

If Collins cannot return in 2017, he will be a candidate for a medical redshirt.

Players who are eligible to earn a medical hardship waiver cannot have played more than 30 percent of his team's games. Collins has played three games, 25 percent of the 12-game regular season. The San Diego native missed the first three games of the season with a broken finger.

While OSU did not put a timeline on Collins' return, senior quarterback Darell Garretson indicated one of his top targets could be out the final five games of the year.
