Shane Edwards has joined Trent Cotchin in being ruled out of tomorrow night's match against Adelaide at Adelaide Oval.

Edwards will miss the Crows clash with hamstring tendonitis, but is expected to return for the game against St Kilda after the bye round.

The Tigers' head of football Neil Balme said Cotchin hadn't reinjured his hamstring but will miss regardless.

"Funny you ask me that, he's not going to play, he's sore. It puts a bit more pressure on, but that's all right," Balme told reporters at Melbourne Airport.

"He's just a bit sore in the hamstring, but it's not the same. I reckon if he hadn't have had the problem before, he would have played.

"The fact we're playing on the Thursday makes it more difficult. If we'd played on Saturday or Sunday [he was a chance], but we won't take the risk."
