FRISCO -- La'el Collins continues to work at right tackle during organized team activities. The third-year offensive lineman said he expects to work exclusively at that position throughout the remaining offseason sessions and at training camp this summer.

The Cowboys need to fill the hole left by veteran right tackle Doug Free's decision to retire. Collins missed most of last season with a toe injury and started at left guard as a rookie in 2015.

Collins said he's feeling comfortable on the right side and that he benefits from playing alongside Pro Bowlers such as left tackle Tyron Smith, center Travis Frederick and right guard Zack Martin.

"The chemistry is there now; it's just as far as getting as many reps as we can together and going out there and working every day, putting it all together and focusing on the little things and just going from there," Collins said.

Said Martin of playing next to Collins: "It's great; it's a new experience; obviously, I've played next to Doug for the last three years. But hopefully I can do what Doug did for me and help him along the way. He's playing a new position, kind of like I was coming in. So as much as I can communicate with him, the better.

"Obviously he's been here, Year 3. Kind of know all about him, what he's about. So just excited to watch him play. He's a fighter; he scratches and claws to get his job done. He's going to be great."

The Cowboys will look at players such as Jonathan Cooper and Emmett Cleary at left guard if Collins' move becomes permanent.
