McClanahan (shoulder) was activated from the injured list Thursday, Tricia Whitaker of Bally Sports Sun reports.
McClanahan missed three weeks with his shoulder injury, but he is ready to return to action and will jump right back into the rotation Thursday night against the Blue Jays. McClanahan has faced Toronto only once this season, and the opponent had few answers for him, as he allowed just one earned run while striking out 10 batters over 7.0 innings to pick up the win back on July 2.
