After a great first four games for the undefeated New England Patriots, Albany native Dion Lewis is now battling an abdomen injury.

Lewis was limited in Thursday's practice, but in typical Patriots fashion, little details have been provided at this point.

Lewis is a major reason why the Pats are 4-0, as he has run effectively out of the backfield and caught the ball well in the passing game.

Lewis has become one of Tom Brady's favorite targets this season. He was an integral part of each win, going for more than 100 total yards from scrimmage against the Steelers and Bills in wins.

He also helped the Pats beat Jacksonville and then had an incredible touchdown reception/run against the Cowboys this past weekend in Dallas.

The Patriots are traveling to Indianapolis this Sunday night for a huge matchup with the Colts. It's the rematch of the AFC Championship and also the Pats chance to take revenge on the Colts for the "DeflateGate" claims.
