The Washington Redskins on Wednesday acquired New England Patriots center Bryan Stork in a trade, the team announced. The Redskins will send the Patriots a conditional seventh-round pick in exchange, according to a person with knowledge of the situation. The trade was made official despite Stork informing the Redskins that he might retire once the two teams reached an agreement, according to two people with knowledge of the situation. The trade was briefly held up as a result but, was on the NFL’s transaction wire Wednesday afternoon.

It was unclear what would have led Stork, who is in his third season, to contemplate retirement. He has had a history of concussion problems dating back to his senior season at Florida State. Stork suffered one earlier this month during Patriots training camp.

Stork, who is still on his rookie contract, would lose $838,500 if he retires. He would forfeit his $600,000 base salary this season and owe the Redskins $238,500 of his signing bonus, prorated for the final two years.

If Stork does not retire, the addition would bolster a weakness at center. The Redskins lack depth at the position behind Kory Lichtensteiger, who missed 11 games because of a neck injury that affected the strength in his left shoulder. They have used left guard Spencer Long as the backup center, followed by Josh LeRibeus and Austin Reiter.

Stork would arrive at Redskins Park with some baggage, however. Stork was kicked out of a joint practice with the Chicago Bears last week in Foxborough after he reportedly swung at Bears linebacker John Timu after an 11-on-11 play.

The 25-year-old has 17 career regular season starts, including six last year. Stork began the season on injured reserve with a designation to return after suffering a concussion and played in just eight games. Listed at 6-4 and 310 pounds, Stork started in Super Bowl XLIX as a rookie and played in 13 games during the 2014 season.

A fourth-round pick (105th overall) in the 2014 NFL draft, Stork was a senior consensus all-America center at Florida State and was awarded the Remington Trophy, given to the top center in the nation, in 2013.
