RICHMOND, Va. — Redskins president Bruce Allen said Monday the team would not reconsider the team's nickname if it became a political barrier to building a new stadium in the nation's capital or elsewhere.The club plays at FedEx Field — which opened in Landover, Md., in 1997 — and has started exploring sites for a new facility, though the FedEx Field lease runs until 2026.Allen, a former Bucs general manager, said the team has spoken with representatives of Washington, Virginia and Maryland about a spot for a stadium.U.S. Interior Secretary Sally Jewell told Washington Mayor Muriel Bowser in April that the National Park Service — which owns the land where the team's former home, RFK Stadium, sits — wouldn't grant a new lease because of objections to the team's name. Owner Dan Snyder has said he will never change the nickname. When asked Monday about possibly revisiting that policy, Allen said, "No." Defending Geno: Injured Jets quarterback Geno Smith was not at fault in last week's locker-room fight that ended with his jaw broken, receiver Brandon Marshall said.
