DUNEDIN, Fla. - Toronto Blue Jays first baseman David Cooper won't be at spring training this year due to a serious back injury, the club announced Sunday.

Meanwhile, right-handed pitcher Tyson Brummett has been added to the big league camp as a non-roster invitee, rather than reporting to the Jays' minor league camp.

Cooper is seeing specialists, hoping for help with a disc issue.

"It's going to be longer than we were hoping," said manager John Gibbons. "So that's bad news."

Cooper split last season between Toronto and triple-A Las Vegas. He hit .300 with four homers and 11 RBIs in 140 at-bats in 45 games with the Jays in 2012.

Brummett was claimed off waivers from the Phillies in October.
