ALLEN PARK — The Lions wrapped up their 10th training camp session on Thursday:

— No sign of Calvin Johnson. Jim Caldwell said he had an excused absence and would not say if Johnson will play in the preseason opener on Saturday.

— Eric Ebron, who did not practice on Wednesday, also did not practice Thursday. He was on the field watching. 

— Safety James Ihedigbo limped off the field at one point, got his right calf looked at by trainers and walked it off. He finished practice and said afterwards that it was no big deal.

— Offensive coordinator Joe Lombardi on Matthew Stafford: “He hasn’t thrown one interception in a team  or seven-on-seven period all during camp. “That’s a credit to him and all the work he’s done.

— Lions signed veteran cornerback Drayton Florence who practiced wearing No. 30. Darius Slay had worn 30, but switched to 23 on Wednesday.

— Ziggy Ansah and TJ Jones remain on the PUP list.
