The Patriots have agreed to sign offensive lineman Brian Schwenke, Field Yates of ESPN.com tweets. Schwenke, a guard/center, spent the last five seasons with the Titans. 
Schwenke missed 23 regular season games from 2013-2015, but he has now turned in back-to-back 16-game seasons. It’s hard to say whether Schwenke is healthier, however, since he has played a whole lot less in the last two years. The 27-year-old started at center for all of his games from ’13-’15, but served as an interior line reserve in ’16 and ’17. Schwenke’s 148 offensive snaps last year were not enough to qualify for a ranking, but his 60.4 overall score from Pro Football Focus left much to be desired.
With the Pats, Schwenke will try to hook on as a backup behind starting guards Joe Thuney and Shaq Mason and center David Andrews.
