Sebastian Georg Vollmer (German pronunciation: [zeˈbasti̯a(ː)n ˈɡeːɔʁk ˈfɔlmɐ]; born 10 July 1984)[1] is a German former professional American football player who was an offensive tackle for the New England Patriots of the National Football League (NFL).

Born in Kaarst, Germany, Vollmer did not start playing American football until he was 14 years old.

He played American football for the Düsseldorf Panther and helped his team to a 25–0 record and two national Junior Bowl wins.

After appearing in the 2003 Global Junior Championships in San Diego, California, he was recruited by college coaches as a 250-pound tight end.

After requiring back surgery as a sophomore, Vollmer switched from tight end to left tackle, where he started 25 straight games for Houston.

He returned in week 2 and rotated with Nate Solder at right tackle but was injured again in the win over the San Diego Chargers.

As Markus Koch was drafted 30th overall by the Redskins in 1986 and helped Washington win Super Bowl XXII two years later, Vollmer is often erroneously credited as the first German ever to be selected in an NFL draft, and further, to win a Super Bowl title.

With Nate Solder out for the season, Vollmer was moved to the left tackle spot, then missed a game due to a concussion.

His autobiography, titled German Champion: Die Geschichte meiner NFL-Karriere, was published on 8 September 2018.
