Blue Jays left-hander J.A. Happ said a package containing a knee brace didn't arrive Thursday as hoped, so Friday will be the earliest he'll try throwing outdoors, according to an ESPN.com report.

Happ said he was told not to increase his throwing activity without the new knee brace.

The former Phillies and Astros pitcher said doctors gave him good reports on the healing of his head injuries. He hopes to return to action next month.
