Calvin Johnson, Eric Ebron practice again

ALLEN PARK, Mich. -- Two of the Detroit Lions' biggest targets returned to practice Friday morning, but it is unclear if either will actually play a snap Saturday night (7:30 ET) against Cleveland.

Calvin Johnson returned from an excused absence Thursday. Eric Ebron missed practice Wednesday and Thursday with an undisclosed injury. Considering the Lions' were essentially just doing walk-through-type motions Friday, there was little harm in either player being out there.

Lions coach Jim Caldwell, though, continued to be coy whether either would play against the Browns. He was like that for all of his players, including how long the starters might end up being on the field.

"It depends, you know. We talk about it in a couple different ways," Caldwell said. "We talk about it in both regards actually because you can't tell. If the opposition gets the ball and they have an eight-minute drive and you’re only going to play a group the first quarter, you’ve got to re-think it. There’s just it kind of depends. We have our parameters set."

While Johnson and Ebron returned to practice, running back Joique Bell was absent with what Caldwell said was a non-injury excused absence for "personal reasons."

No matter who plays and who doesn't, it would be surprising to see any Lions starter on the field for more than a couple of offensive or defensive series during the preseason opener.

As for what fans could see offensively from Detroit, expect a lot of different formations and personnel packages.

"Pretty versatile offense but efficiency is the thing that we’re looking for, putting points on the board," Caldwell said.
