News: Riddick (hamstring) practiced fully Thursday, Tim Twentyman of the Lions' official site reports.
Impact: It's an upgrade in participation for Riddick, who was a limited participant Wednesday. Meanwhile, fellow running back Reggie Bush did not practice Thursday after being limited Wednesday. We'll revisit the status of both backs Friday, with Riddick's chances of providing Week 8 fantasy utility (while working with Joique Bell, who is not in the team's injury report) largely tied to Bush's availability.
News: The Lions plan to have Jones (shoulder, PUP list) participate in practice soon, mlive.com reports.
Impact: "We're going to bring him off (the physically unable to perform list) sometime in the next few weeks and let him practice, and we'll see what he does," GM Martin Mayhew noted Thursday of Jones, who the Lions drafted in the sixth round of the 2014 NFL Draft. Assuming he re-proves his health, Jones is a candidate to carve out a role out of the slot in the Lions' offense, but a wait-and-see approach remains in order from a fantasy perspective.
News: Fauria (ankle) did not participate in Thursday's practice, Kyle Meinke of MLive.com reports.
Impact: Fauria sat out along with fellow tight ends Eric Ebron (hamstring) and Brandon Pettigrew (foot), and no one out of that trio is a lock to play in Sunday's contest in London. Kellen Davis and Jordan Thompson would be next in line for reps at tight end if the aforementioned options are unable to improve prior to Week 8's contest against the Falcons.
News: Pettigrew (foot) did not participate in Thursday's practice, Kyle Meinke of MLive.com reports.
Impact: Pettigrew joins both Eric Ebron (hamstring) and Joseph Fauria (ankle) in the group of tight ends on the DNP list, leaving Detroit looking potentially thin at the position for their Week 8 contest in London. If none are able to improve by Friday, look for Kellen Davis or Jordan Thompson to see additional reps on Sunday.
News: Ebron (hamstring) did not participate in Thursday's practice, Kyle Meinke of MLive.com reports.
Impact: Ebron has now missed his second straight day of practice, which doesn't bode well for his chances of suiting up Sunday against the Falcons in London. Friday's injury report should paint a clearer picture, however. With Joseph Fauria (ankle) and Brandon Pettigrew (foot) also sitting out Thursday's practice, the Lions may be forced to rely on Kellen Davis or Jordan Thompson in Week 8.
News: Bush (ankle) did not participate in Thursday's practice, Kyle Meinke of mlive.com reports.
Impact: Bush was limited Wednesday, but sat out Thursday, likely in an effort to give his ailing ankle some extra rest. This report clouds his status for Sunday, but Friday's injury report should provide more precise clarification on the matter. If he's limited Sunday against the Falcons, look for Joique Bell to take a lead role in the Lions' backfield.
News: Johnson (ankle) "did much more" at Thursday's practice, Tim Twentyman of DetroitLions.com reports.
Impact: Johnson sported a helmet for the first time this week, and showed progress by demonstrating the ability to cut and run routes. The news is surely encouraging, but it remains unclear if he'll be able to suit up for Sunday's Week 8 matchup with the Falcons. Considering Detroit will have a Week 9 bye, Johnson will likely have to continue to make significant strides in order to avoid being held out.
News: Waddle kept playing after banging his head on the ground late in last week's victory over the New Orleans Saints, even though the team knew a concussion was possible.
Impact: Waddle was knocked down while blocking during an extra-point attempt after Corey Fuller had scored in the 24-23 comeback win over the Saints. He was then on the field at right tackle when quarterback Matthew Stafford took a knee to end the game on the next possession. Lions coach Jim Caldwell said Thursday the team knew when the concussion happened, but then said the team's doctors weren't sure right away.
