The Winnipeg Blue Bombers bolstered their secondary by signing import defensive back Davin Bush on Monday.

Contract terms were not disclosed.

Bush, 29, posted 33 tackles and a team-high five interceptions in 17 games for the Saskatchewan Roughriders last season.

"Bush is a solid, experienced defender who will add some veteran savvy to our defensive secondary," said Blue Bombers general manager Brendan Taman in a statement.

Bush has totalled 190 tackles, 15 interceptions, two touchdowns and one fumble recovery in 75 games over six CFL seasons, all with Saskatchewan.

"His addition will make a solid unit even better," Taman said.

Bush, a Miami native, is the second defensive back to bolt Saskatchewan in as many weeks.

Omarr Morgan, a three-time CFL all-star, joined the Edmonton Eskimos last Saturday.
