Sen'Derrick Marks injury: Jaguars DT to have MRI

Jacksonville Jaguars veteran defensive tackle Sen'Derrick Marks will have an MRI on his shoulder after leaving the game with an injury. Marks seemed to hurt his shoulder in the first quarter of the Jaguars loss to the Detroit Lions on Friday evening, taking his pads off on the sideline and icing it down.

The team didn't indicate one way or another if Marks' injury was serious or not, but I would not anticipate him playing the fourth preseason game against the Atlanta Falcons on Thursday, regardless of the outcome of his MRI.

Marks has been arguably the Jaguars best defensive player since he signed as a free agent on a prove it deal last season. He was certainly the teams most consistent disruptor and earned himself a new four-year contract in the process.

He's carried that play on through the 2014 preseason with some big plays and muddling things up in the backfield for opposing offenses, so hopefully his injury is only minor.

UPDATE: Head coach Gus Bradley announced on Sunday that the timetable for Marks' return could be a short one and that it's possible he won't miss the regular season opener.

Gus says they hope Marks and Beadles will be able to practice next week for Opening Day
