SPARTANBURG, S.C. – General manager Dave Gettleman was surprised when he learned offensive tackle Jonathan Martin planned to retire, but the focus has quickly shifted to what's next for the Panthers' offensive line.
"We were pleased to have Jonathan on the club and obviously these other guys have to step up," Gettleman said. "It's the responsibility for us to have as deep a roster as possible, and it's the responsibility for the coaches to get them ready.
"We'll just keep moving on. That's what we do."
Martin, whom the Panthers claimed off waivers from the San Francisco 49ers, was a candidate to back up left tackle Michael Oher.
