The official St. Louis Rams Twitter account has released the details of today's practice:
@STLouisRams: WR Danario Alexander aggravated hamstring a bit yesterday and did not practice after he was limited Wednesday.
@STLouisRams: LB Bryan Kehl is battling an ankle injury. He was limited. RB Jerious Norwood also still battling hamstring injury, also very limited.
Alexander, the undrafted free agent out of the 2010 Draft, has suffered with a variety of injuries throughout his playing career and has also struggled to produce in the 2011 NFL season, catching only 16 passes through five starts.
Bryan Kehl played at the strong side linebacker position in last week's surprising win over the New Orleans Saints, but may able to play again this week against the Arizona Cardinals.
Meanwhile, Sam Bradford has practiced again, but was limited to drills.
Also appearing on the injury list, DT Darell Scott and RT Jason Smith continue to miss practice while recovering from concussions.
