Dolphins offensive tackle Austin Jackson will miss at least the next few weeks after he was "stepped on" and suffered a lower leg injury.

The Miami Dolphins added offensive lineman Germain Ifedi on Sunday, adding depth to a line that saw starting right tackle Austin Jackson injured on Friday. Ifedi was one of five offensive linemen to tryout for the Dolphins on Saturday. Ifedi joined the team on the practice field on Sunday, wearing number 62.

Austin Jackson’s absence means the Dolphins aren’t likely to have their starting offensive line together for the joint practices and preseason games against Chicago and Detroit.
