Reed missed some practice time due to a hamstring injury Thursday, Ryan O'Halloran of The Denver Post reports.
The severity of Reed's hamstring injury remains unclear, but head coach Vic Fangio did say that Reed would likely miss Friday's practice as well. Aaron Wallace and Ahmad Gooden figure to see additional reps while Reed is sidelined.
Reed looks to be the third outside linebacker at this point in the preseason, Benjamin Allbright of KOA News Radio reports.
Backup edge rushers Shane Ray and Shaq Barrett both departed this offseason, leaving a void behind Von Miller and Bradley Chubb. Though unheralded and undrafted out of Nevada, Reed has been one of the most pleasant surprises of Denver's first two preseason games. Reed has recorded a sack in each contest and eight tackles overall. Reed's a bit of a tweener, but he managed to rack up 126 tackles, 25.5 tackles for loss and 16 sacks in his final two seasons in Nevada's 3-3-5 scheme. That production seems to be carrying over to the pros.
