FOXBORO, Mass. — A concussion continues to keep New England Patriots starting center Bryan Stork sidelined.

Stork didn’t practice Monday because of the head injury, according to the Patriots injury report — the first of the 2015 season. Stork missed all four Patriots preseason games due to injury.

Here’s the full report:

If Stork can’t play Thursday in the Patriots’ Week 1 matchup with the Pittsburgh Steelers, veteran Ryan Wendell likely will start at center.
