Left tackle Donald Penn signed a one-year deal to return to the Oakland Raiders in 2016.
Penn, 32, will pair with free-agent signee Kelechi Osemele to give the Raiders a strong front five. Osemele can play guard and tackle and signed a five-year, $58.5 million contract on the first day of free agency. He started at left tackle in December 2015 for the Baltimore Ravens with Eugene Monroe injured but was primarily a guard before that.
