Chekwa (leg) was sidelined again during Sunday's practice, James Walker of ESPN.com reports.
Chekwa has been dealing with a lingering leg injury for roughly two weeks now and has yet to shed light on a potential return date. The 27-year-old cornerback is slated to be a reserve for the Dolphins during the upcoming season, so the team is still hoping to give him some live game action sometime during the team's final two preseason matchups.
