ALLEN PARK — Ndamukong Suh reported to training camp in impressive shape according to those who have seen him.

The Detroit Lions defensive tackle also reported without having a contract extension done, but coach Jim Caldwell said that will not be a distraction.

“No. 1, he’s in the best shape he’s ever been in,’’ Caldwell said on Sunday. “He’s got a great attitude. You guys will have a chance to talk to him at some point in time, he’ll speak for himself. I don’t think he’s going to let anything distract him. I’m not worried about it in that regard because Tom (Lewand) and obviously Martin (Mayhew) and ownership will get that taken care of.’’

Caldwell said he’s “absolutely” sure that Suh will reach a long-term agreement.

“I’m always optimistic,’’ Caldwell said. “I think you know me by now. Without question they’re working at it and something will be done at the appropriate time.’’

Center Dominic Raiola said the players won’t try to urge Suh into a new deal.

“I don’t think there’s much talking to him,’’ Raiola said. “Right now he’s under contract with the Detroit Lions and he’s coming to camp. He’s here, he’s a Detroit Lion and I’m excited for that. 

“The guy looks more like Adonis now. I think he cut out more body fat and put on more weight which is scary. He’s an exceptional player, one f the best d tackles we play against all year long,’’ Raiola added.

Linebacker Stephen Tulloch echoed the comments. 

He doesn’t see the lack of a new contract as a distraction and he wants Suh playing well in front of him.

“As long as I’m here, I’d like to have him here,’’ Tulloch said on Sunday.
