Heres the latest injury news you need to know.RT Blake MillerOn Sunday, Miller appeared to be limited to only individual drills. Thankfully, Campbell confirmed that was just being precautionary, and Miller is expected to be back into the full lineup on Monday.Hell roll today. We dont anticipate any issues, Campbell said. He wanted to do more (Sunday). We kinda held him back. EDGE Derrick MooreThe news wasnt as good for Lions second-round pick Derrick Moore, who left Sundays injury with a groin injury. Campbell said he is expected to miss about 7-10 days with a minor strain. Obviously, in the long-term, thats not a big deal for any player to miss a couple weeks of practice, but this is a valuable time of year for a rookie like Moore.Its unfortunate for all of the rookies, Campbell said. These reps are valuable. You miss valuable time, but it also is what it is. LB Jimmy Rolder Campbell confirmed earlier reports that Rolder will be out for a while with a hamstring injury. That said, the Lions coach made sure to reiterate that its not a season-ending injury for Detroits fourth-round pick. Its a little unfortunate, but at the same time, its not a season-ender, Campbell said. So thats good news. TE Miles KitselmanThe Lions undrafted rookie tight end left Sundays practice with a leg injury and will also be out a while. For someone already on the roster bubble, this is a tough blow to his first season.
