Seattle Seahawks cornerback Richard Sherman is still recovering from the Achilles injury that ended his 2017 season, and the four-time Pro Bowler will undergo offseason surgery on his other heel to address a different injury.
According to Carroll, Sherman should recover from the heel surgery within four to six weeks.
Sherman's ruptured Achilles is the far bigger concern.
Carroll said Tuesday the 29-year-old should be out of the walking boot on his right foot within the week, per the Seattle Post-Intelligencer's Michael-Shawn Dugar. In a question and answer session with fans he uploaded to YouTube, Sherman said he's likely to return in May or June:
Even if he's healthy when the Seahawks kick off the 2018 season, there's a question as to whether he can be an All-Pro cornerback again. The effects of the injury can linger well after a player fully recovers. Arian Foster retired altogether a year after rupturing his Achilles in October 2015.
Sherman's injury casts further doubt on his future in Seattle as well. Seahawks general manager John Schneider confirmed in April the team had at least considered trading Sherman, so the idea Seattle would move on from him in the months ahead isn't all that crazy.
The Seahawks could save $11 million against $2.2 million in dead salary cap money by releasing him before June 1, per Over the Cap.
The heel surgery adds to what was already an uncertain offseason for Sherman.
