Date:

49ers signed DT Sen'Derrick Marks, formerly of the Jaguars.

Marks, 30, was released by the Jaguars back in March. He hasn't been the same productive player since tearing his ACL in 2014, but Marks has experience in DC Robert Saleh's scheme after playing for Gus Bradley in Jacksonville.
Aug 23 - 1:13 PM

Jaguars released DT Sen'Derrick Marks.

Jacksonville had way too much money tied up in the defensive line after signing Calais Campbell, and 2016 fourth-rounder Sheldon Day is ready to take on Marks' snaps. The move saves Jacksonville $4.475 million against the cap. Marks has not been the same since he tore his ACL in 2014.
Mar 9 - 3:52 PM

Ryan O'Halloran of the Florida Times-Union reports the Jaguars are attempting to trade DT Sen'Derrick Marks.

Leaking you are attempting to trade a player is the first step in a waltz which usually ends with the player's release. Marks was outstanding in an 8.5-sack campaign in 2014, but he tore his ACL during the final game of that season and has never been the same. With Marks now 30 and owed almost $4.5 million in the final year of his deal, it is unlikely Jacksonville will find a trade partner. Cutting Marks will save the Jags $4.475 million against the cap.
Mar 4 - 9:07 AM

Jaguars DT Sen'Derrick Marks (triceps) took part in individual drills at Friday's OTAs.

It's the first time Marks has practiced with a helmet on all offseason. A torn triceps limited Marks to just four games in 2015 but it looks like he'll be close to 100 percent by the time training camp rolls around. Jacksonville's defensive line should be much improved this year with Marks and Dante Fowler both healthy and free agent signing Malik Jackson providing an additional pass-rushing presence.

Jaguars DT Sen'Derrick Marks (torn triceps) expects to be ready for training camp.

Now 29, Marks missed the first five games of last season as he recovered from a torn ACL. He then tore his triceps in his fourth game back. If he can get healthy, Marks will likely contribute as a situational pass rusher for Jacksonville's suddenly-deep front seven.

Jaguars DT Sen'Derrick Marks (triceps) expects to be a full participant for OTAs.

Marks' recovery from triceps surgery is going well and the hope is that he'll be back to full strength by April. He had his brace removed last week and began "activating" his triceps on Wednesday. Marks suffered a season-ending triceps tear in only his fourth game back after missing the first five games of 2015 while recovering from a torn ACL. If -- and it's a fairly big if -- the Jags can get Marks healthy and Dante Fowler to play at the form he was supposed to coming out of Florida, Jacksonville's pass rush could turn around in a hurry.

Jaguars placed DT Sen'Derrick Marks on injured reserve with a torn triceps, ending his season.

Marks' second opinion confirmed he wouldn't be ready for the season's final seven games. It's a major blow for a player who tore his ACL late in 2014. Marks has been a useful player, but his recent injury history could have the Jags looking to move on. He turns 29 in February, and is due $3.45 million in 2016.
Tue, Nov 17, 2015 01:21:00 PM

Jaguars DT Sen'Derrick Marks suffered a torn triceps Week 10 against the Ravens.

Marks is likely done for the year, but he is seeking a second opinion. Marks suffered a torn ACL the final game of 2014 which kept him out the first five weeks of this season. Marks ramped up his playing time in the last three games, but he had yet to make a real impact. Another full offseason of recovery would likely be good for his surgically-repaired knee.
Mon, Nov 16, 2015 01:09:00 PM

Jaguars DT Sen'Derrick Marks exited Week 10 against the Ravens with an elbow injury.

Marks sat out the entire second half and underwent an MRI following the game. On a short week, it is likely Marks sits out Thursday against the Titans. Marks missed the first five weeks of the season recovering from a 2014 ACL tear. He has just four tackles after recording 8.5 sacks last season.
Sun, Nov 15, 2015 10:28:00 PM

Jaguars DT Sen'Derrick Marks (knee) is probable for Week 6 against the Texans.

He's expected to make his season debut after tearing his ACL late last season. We saw with Geno Atkins last season that it can be hard for interior linemen to have their same explosiveness and disruption ability coming off major knee surgery. So, even though Marks was one of the best interior pass rushers in the league before getting hurt last season, expectations need to be tempered.
Fri, Oct 16, 2015 11:12:00 AM

Jaguars coach Gus Bradley said "there is a chance" DT Sen'Derrick Marks will play this week against the Texans.

Marks has been practicing on a limited basis since Week 3, but he got in his first full session of the season on Wednesday. Marks was one of the best interior pass rushers in the league last season.
Thu, Oct 15, 2015 09:48:00 AM

Jaguars DT Sen'Derrick Marks (knee) is doubtful for Week 3.

Marks was cleared for practice this week, getting in three straight limited sessions. He won’t play against the Patriots, but should be close to fully healthy. Marks is on track for a Week 4 return.
Sat, Sep 26, 2015 03:11:00 PM

Jaguars DT Sen'Derrick Marks (knee) has been ruled out for Week 2.

Trying to come back from last year's late-season ACL tear, Marks practiced on a limited basis Wednesday, but was held out the rest of the week. Marks is a difference maker when healthy, so his absence doesn't hurt the outlook for Ryan Tannehill, Lamar Miller, Jarvis Landry, and Co.
Fri, Sep 18, 2015 02:00:00 PM

Jaguars DT Sen'Derrick Marks (knee) did not practice on Thursday.

Marks did not practice on Thursday, after doing so on a limited basis on Wednesday. The former Auburn Tiger was scheduled to miss Thursday's session, and HC Gus Bradley commented, "He went through individual drills and moved around pretty good... he’s on the right track." Marks remains questionable for Week 2, but is projected to be a DL3 (DT1) in fantasy leagues when he returns.
