Falcons coach Dan Quinn confirmed OT Sam Baker (knee) is a candidate for the starting left guard job.
Baker spent all last year on I.R. with a torn patellar tendon. He also missed 12 games in 2013, and is best suited for the inside at this stage. Seven months removed from knee surgery, Baker is questionable for training camp.
Patriots DT Sealver Siliga underwent offseason surgery.
This being the Patriots, injury details aren't yet known. Siliga missed nine games with a foot injury last season. He's currently in a walking boot and should be considered questionable for OTAs. With Vince Wilfork gone, Siliga, Dominique Easley, and Alan Branch are the Patriots' top interior linemen.
The Vikings have reached out to free agent ILB Brandon Spikes.
The Vikings have interest in Spikes, but are reportedly unwilling to meet his asking price. An early-down run stopper, Spikes would be a major upgrade at the MIKE spot for Minnesota. The Bills also haven't ruled out re-signing Spikes.
The Texans will move OG Ben Jones to center.
Jones started all 16 games at left guard last season. The Texans are staying in-house to replace Chris Myers, moving Jones to center and starting second-year LG Xavier Su'a-Filo. 25-year-old Jones is in the final year of his rookie deal.
Xavier Su'a-Filo is the leading candidate for the Texans' left guard job.
Su'a-Filo appeared in 13 games as a rookie, making his only start at right guard. He's expected to take over for Ben Jones on the left side, with Jones replacing Chris Myers at center. Houston should remain an elite run-blocking team in 2015.
Tahir Whitehead is expected to compete for the Lions' strong-side linebacker job.
Whitehead started 13 games in place of Stephen Tulloch last year, finishing with 86 tackles and grading out as PFF's No. 14 inside linebacker. With Tulloch healthy, Whitehead will need to beat out Kyle Van Noy for a starting job. Whitehead can also back up at all three linebacker spots.
Lions MLB Stephen Tulloch (knee) is questionable for OTAs.
Tulloch is six months removed from his torn ACL. He has a chance to be ready for spring workouts, but is expected to be held out until training camp. Tulloch will return as Detroit's starting MIKE linebacker when healthy, with Kyle Van Noy and Tahir Whitehead competing on the strong side.
Mike Remmers is expected to open training camp as the Panthers' right tackle.
Remmers made seven starts (including playoffs) last year, grading out as a top-30 pass blocker by PFF. He should face competition from Nate Chandler and Jonathan Martin. Michael Oher is the current favorite to start at left tackle.
