The Athletic reported that Baldwin was running sprints by himself Thursday, while station KIRO-7 observed that Seattle’s leading receiver “looks sharp” while going through individual drills.
Seahawks coach Pete Carroll has maintained that he expects Baldwin to be on the field for the regular-season opener against the Denver Broncos on Sept. 9.
Baldwin arrived at training camp with a sore knee and was expected to miss at least two weeks.
