• The Lions signed wide receiver Billy McMullen and released offensive guard Toniu Fonoti on Tuesday.  McMullen was just released by the Seahawks, and with the Lions' wide receivers having a bad case of the injury bug, the team felt it was necessary to add depth to that position.
• Bryant Johnson finally practiced for the first time in training camp.  He only took part in individual drills for the most part, but that seems to be the Lions' protocol when injured players return to practice.  Jordon Dizon, who also returned to practice today, only participated in individual drills as well.
• In case you need to get caught up on the current list of injuries, here is what it looks like, as compiled by Tom Kowalski:
  

  Others still sidelined include receivers Calvin Johnson (thumb), Dennis Northcutt (hand) and John Standeford (hamstring), tight end Brandon Pettigrew (thigh), cornerback Keith Smith (groin), tight end Casey FitzSimmons (ankle), linebacker Zack Follett (shoulder), safety Daniel Bullocks (knee), tackle Lydon Murtha (undisclosed), safety Marquand Manuel (calf) and running back Maurice Morris (hamstring).

  Hopefully they won't be added to the list, but Anthony Henry and Dewayne White both left practice today when they had "thigh bruises tighten up."
• Calvin Johnson's thumb injury is only a sprain, thankfully.
• Jim Schwartz already has an idea of who will start in the Lions' preseason opener on Saturday, but he probably won't announce that piece of news until later in the week. 
• Safety Daniel Bullocks is out indefinitely with a sore knee.  He was checked out by Dr. James Andrews recently and nothing new appears to be wrong with Bullocks' knee.  The fact that it is still sore, however, has caused Schwartz to "shut him down for a little while."  Hopefully Bullocks' knee eventually gets better, allowing him to return before the regular season, but things don't look all that promising right now.
• There were quite a few mental lapses during practice today.
• Lloyd Carr and Jeff Daniels were at practice today.

• MLive.com's Philip Zaroo has a full rundown of yesterday's practice.
• Jim Schwartz sort of complimented Rick Porcello's body slam of Kevin Youkilis in last night's Tigers-Red Sox game.  (Can you believe that Porcello was not only ejected, but suspended 5 games?  Youkilis got 5 games as well, which is just ridiculous.  There were no warnings issued before Porcello plunked Youkilis, and what's more, it's not Porcello's fault Youkilis charged the mound.  I don't understand how they can get equal suspensions when Youkilis threw his helmet at Porcello.  It seems like the Tigers got the shaft last night and again today with this ruling.)
• One of the reasons Shaun Smith decided to sign with Detroit was that his best friend and ex-Lion Shaun Rogers spoke highly of the team.  That's a bit surprising considering the circumstances of Rogers' departure from the Lions, but Smith even said Rogers "wishes he could come back here now."
• SI.com's Don Banks wrote about the Lions and the practice he attended on Monday in Allen Park.
• If you want to watch the Lions play at Cleveland on August 22, you can get tickets for only $16.
• Charles Rogers supposedly is running the 40-yard dash in 4.4 seconds on a consistent basis, according to his trainer via Jemele Hill.  I will believe that when I see it.
