One of the NFL’s more productive defensive linemen was added to his club’s injury report on Friday.
Browns left defensive end Ahtyba Rubin missed practice with a calf injury Friday and is listed as questionable for Sunday’s game vs. the Dolphins.
Rubin, 27, has been a dependable core performer for the Browns the last three seasons. He notched more than 80 tackles — as an interior lineman, no less — in 2010 and 2011. In 13 starts in 2012, Rubin recorded 44 tackles, defended two passes and notched two sacks.
Second-year pro John Hughes is listed as the top backup to Rubin.
Rubin wasn’t the only Browns defensive starter not to practice Friday. Right cornerback Buster Skrine (shoulder) is questionable for Miami. Ex-Falcons corner Chris Owens is next up on the depth chart if Skrine cannot play.
Including Skrine, the Browns list just four cornerbacks on their depth chart.
