Jonathan Cannon: Everything you need to know

The White Sox activated Cannon (hip) from the 15-day injured list Wednesday and optioned him to Triple-A Charlotte. Cannon made a couple rehab appearances for Charlotte after overcoming a hip injury, getting rocked for 10 runs over five innings. He'll remain with Charlotte in a swingman role rather than joining the big club now that he's healthy again.

Cannon (hip) threw a bullpen session Wednesday and could begin a rehab assignment shortly, MLB.com reports. Cannon went to the injured list April 14, but a clear timeline for his return was never established. That remains the case, as there has been nothing reported about his response to the bullpen session or when he will throw again. However, because a rehab assignment will be required, Cannon will be sidelined at least into early May.

The White Sox placed Cannon of the 15-day injured list Tuesday with right hip inflammation. Cannon had to be pulled from Sunday's start against the Royals due to the injury in what was his first outing of the season in the majors. The injury should heal with rest, but it's unclear when Cannon might be game-ready again and it's not a given that he'll rejoin the big-league rotation when he's physically ready.
