The San Francisco 49ers will have two more players back for practice on Sunday. The team announced they have activated linebacker Aaron Lynch, and center Marcus Martin. Lynch was on the PUP list due to a hamstring injury suffered during the offseason workout program. Martin was on the NFI list due to a rolled ankle suffered away from the 49ers offseason workouts.

Lynch will compete at outside linebacker, although he conceivably has the frame to develop into a defensive end. He lost a lot of weight due to an Adderall prescription, weighing 249 pounds at the combine. With his 6'5 frame, there is room for more weight. I don't anticipate a defensive end role anytime soon, but expect the 49ers to continue working with him to get into the 260 range.

Martin will compete with Daniel Kilgore at center, but could also potentially get some work at either guard position. Kilgore entered the offseason as the front-runner to start at center, and all indications are that he will probably hold that job early in the season. On Saturday, Greg Roman was asked about changes on the offensive line, and he specifically mentioned Kilgore at center. Martin was on the NFI list through yesterday, so of course Kilgore would have the clear edge. I do think Martin has a great chance of becoming the starting center in the future, but I also think 2015 is more likely at this point.

In coming off the NFI and PUP lists, the two players can begin taking part in practice. More than likely they'll take part in walkthroughs for now, and then add in padded practice as we move forward. Baalke discussed this on Saturday in regard to Ellington. Ellington was activated off the NFI list, but the 49ers have slowly worked him back. Look for Martin and Lynch to follow the same pattern.
