New England Patriots right tackle Sebastian Vollmer is working back from offseason shoulder surgery, a source tells ESPN Boston’s Mike Reiss.

Vollmer underwent surgery to repair a torn labrum shortly after Super Bowl XLIX, and shortly after the 30-year-old bookend started 18 of the last 19 games for New England.

Resting for only the regular-season finale against the Buffalo Bills in January, the injury did not appear to affect the former second-round pick’s performance in 2014. Pro Football Focus graded Vollmer out as the 11th-ranked tackle in the league during his seventh NFL season, after he saw his sixth NFL season end on injured reserve with a leg injury in October of 2013.

As it currently stands, the 6-foot-8, 320-pounder’s prognosis for 2015 appears on schedule. Vollmer has been rehabbing at Gillette Stadium, according to Reiss, who notes the Houston product is expected to be ready “when it counts.”

Vollmer is joined by guard Ryan Wendell, defensive tackles Sealver Siliga and Chris Jones, as well as linebacker Dont’a Hightower on the list of Patriots known to be recovering from offseason procedures.
