The Toronto Blue Jays are on the outside of the American League playoff picture, but a Josh Donaldson trade may now be more unlikely.

Donaldson has only played in 36 games this season and recently suffered a setback in his recovery from a calf injury.

He suffered an acute strain while taking groundballs in preparation for a rehab game. The Blue Jays will re-evaluate him in three weeks.

That puts Donaldson's return to the Major Leagues at least 4-6 weeks away.

The non-waiver trade deadline is July 31.
