While perfect so far for the 2015 regular season, the New England Patriots took a blow after learning that Nate Solder will miss the rest of the year with a torn biceps. Solder, the Patriots’ starting left tackle, was one of the primary blind side protectors of star quarterback Tom Brady.

Solder will reportedly go under the knife for the biceps injury, according to a tweet from Jim McBride of the Boston Globe. McBride added that the Patriots have claimed defensive back Rashaan Melvin, who was released by the Baltimore Ravens, off waivers to take Solder’s roster spot.

Solder was the Patriots’ first round pick in the 2011 NFL Draft or the 17th overall selection. The 27-year-old offensive tackle is seen as a vital piece in the Patriots’ recent success in previous years and has helped New England to two AFC championships (2011 and 2014) and winning Super Bowl XLIX earlier this year.

Solder tried to remain positive despite the injury and thanked his fans on social media Twitter.

In 67 games played in the regular season throughout his NFL career, Solder has started 64 games. The Patriots are currently undefeated this season at 4-0 with wins over the Pittsburgh Steelers, Bufallo Bills, Jacksonvill Jaguars and Dallas Cowboys.
