Four injury situations to monitor early this week:
Cody Brown, OLB, Cardinals: Arizona's second-round draft choice suffered a wrist injury in the second exhibition game. Brown's agent, Nate Haber, used his Twitter account to say Brown would miss his entire rookie season. Haber: "It appears to be a devastating, rare injury that will sideline him for his rookie season. He is staying strong in this tough time and will do everything he can to return stronger than before." The Cardinals hoped Brown's presence in the rotation would upgrade their pass rush.
Adam Snyder, RT, 49ers. Snyder suffered injuries to his right knee and ankle during the second exhibition game. He was reportedly walking without a limp after the game. The 49ers expect to have MRI results Monday. Snyder has exceeded expectations this summer. Losing him for an extended period would set back the offensive line and force Marvel Smith into action.
Jacob Bell, LG, Rams. Symptoms from a concussion suffered 10 days ago have not cleared, leaving Bell on the sideline until they do. The plan was for Bell to resume running this week, but those plans are on hold. "He still has some symptoms, so we're just going to kind of slow it down with him," coach Steve Spagnuolo said Sunday.
Chris Spencer, C, Seahawks. The fifth-year center suffered an injury of unknown severity to his left quadriceps Saturday night. Spencer has played a full 16 games in two of the past three seasons, but injuries have periodically sidelined him during offseason practices and training camp. Max Unger or Steve Vallos could move into the lineup.
