ALLEN PARK —  Because LaAdrian Waddle will start training camp on the physically unable to perform list, there is a question for the Detroit Lions at right tackle.

Coach Jim Caldwell does not seem too concerned about the position.

“I think all in all we’re going to be all right (at right tackle). (Cornelius) Lucas played a lot of football for us and played well. He had ups and downs but he played well for us. We have some young guys who are going to be alright too,’’ Caldwell said on Friday.

As a rookie, Lucas started three games at tackle last season due to injuries to Waddle. He didn’t name the young guys but Michael Williams, who made the transition from tight end, could be one and rookie Corey Robinson could be another.

Waddle underwent ACL surgery in mid-January. There is no timetable for his return according to Caldwell.

While there were reports that former Lions right tackle free agent Gosder Cherilus had visited the Lions, but Caldwell would not comment.

Overall Caldwell can’t wait to see the new-look offensive line go to work in pads.

The Lions open training camp on Monday and will don pads later in the week.

“Very interested in seeing how they work together, it’s a great group of guys who have the kind of attitude and work habits you like to see,’’ the Lions coach said.

With Dominic Raiola and Rob Sims gone, there are openings at left guard and center. Travis Swanson is expected to start at center with Manny Ramirez and Laken Tomlinson battling at left guard. Riley Reiff will be at left tackle and Larry Warford is expected to start again at right guard.

“We have a veteran that’s in the mix with Manny (Ramirez). We have a young player that has an immense amount of talent in Laken Tomlinson and on down the line there are a number of guys who have some potential,’’ Caldwell said. “We want to see how they jell, how they work together. How Larry (Warford) works with the rest of the crew and Reiff, etc. It’s going to be a lot of fun watching those guys develop and some pretty good battles against the defense as well. You’ve got a defense that’s out to prove itself.’’
