Patriots sign offensive lineman Hill

The Patriots added some depth on the offensive line on Wednesday morning, signing rookie Kyle Hill.

Hill, a four-year starter at left tackle Duke, went undrafted in April.

The 6-foot-6, 306-pounder played and started in 10 games during the 2011 season, and finished his collegiate career with 46 starts.

The Patriots have been down a number of offensive tackles in recent days, with Sebastian Vollmer (PUP) being joined by Kyle Hix and Matt Kopa on the sidelines.
