49ers' Dre Greenlaw: Remains injured heading into camp

Greenlaw (hamstring) remains injured head into training camp.

Greenlaw injured his hamstring in the 49ers' loss to the Rams in the NFC Championship Game, and the team has yet to provide any updates on the potential starting linebacker. The 25-year-old appeared in just six games (including playoffs) due to injury last year, after combining for 178 tackles in his first two seasons in the NFL. If healthy, Greenlaw will compete with Azeez Al-Shaair for the more prominent starting weakside linebacker role in defensive coordinator DeMeco Ryans' nickel-heavy scheme.
