Dolphins cornerback Trill Williams played only one game last season. But he had worked his way up the depth chart and was expected to contribute as a top backup this season.
Williams, though, was carted to the locker room late in Saturday night’s preseason game, Daniel Oyefusi of the Miami Herald reports.
With 1:52 remaining, Williams tackled Deven Thompkins for a 5-yard loss on a throw from Kyle Trask. Williams immediately grabbled his left knee after the open-field stop.
He appeared to be in tears as he left the field.
The Dolphins did not provide an immediate update on Williams.
UPDATE 11:03 P.M. ET: Dolphins coach Mike McDaniel said there is concern for Williams’ “lower extremity” injury, but the team will know more Sunday after further medical testing.
