Noticeably absent from last week’s informal workouts at Country Day was defensive tackle Ndamukong Suh.

While Kyle Vanden Bosch mostly put the four-day program together, he got little response from defensemen. No linebackers were present and just a few defensive backs.

Now in their defense, there wasn’t a lot of lead time and it was voluntary.

If you follow Suh on Twitter you know he’s a busy guy with all his marketing and promotional work. Seems he’s never in one place too long. Today he tweeted from London, England.

We’ll give him a pass for not attending the workouts last week.

But when the Lions crank it up again the week of June 6, it will look bad if he’s not there. He’s supposed to be a team leader. This is one reason he’s paid the really big bucks.

The only rookie present was WR Titus Young, but Vanden Bosch took the blame for that.

“I wasn't able to make contact with any of the rookies,’’ Vanden Bosch said. “I just had an email list of the guys who were on the team last year. Those are the only ones I talked to.’’

Plus there was an NFL event for selected rookies in Los Angeles late last week.

It will be interesting to see who shows up the week of June 6.
