Free-agent Lions OT Jason Fox is visiting the Chiefs today, per league source.— ProFootballTalk (@ProFootballTalk) March 31, 2014
He was a fourth round pick with the Detroit Lions in 2010. He started three games last season, the only three starts of his career. Sounds like he's had a history of injuries.
"Fox won the starting right tackle job in training camp last year, but he just couldn't stay healthy," Sean Yuille of Pride of Detroit wrote me. "That's been the story of his entire career. He dropped in the draft because of injury concerns, and he dealt with injuries throughout his first two years in the league. He did manage to stay healthy throughout the 2012 season, but he got hurt in his first career start last season. He then got hurt again when he returned later in the year, and the Lions went with an undrafted free agent who outperformed him from that point forward.
"Fox isn't a bad backup by any means, but because you can't depend on him to stay healthy, he's not a great option if you're looking at him as a starter."
The Chiefs starting tackles appear to be Eric Fisher (left) and Donald Stephenson (right). Last season, Fisher and Branden Albert were the starters with Stephenson filling that important role as the third tackle. With injuries, Stephenson has started seven games in each of the last two seasons, so that's clearly an important backup role.
Also signed this offseason was Jeff Linkenbach, former Colts lineman who has experience at tackle and guard.
