The third-year receiver was immediately surrounded by athletic trainers, with one trainer sitting up Goodwin on the ground and holding him from behind while another trainer wrapped a towel around his neck.
After several minutes of sitting on the field, Goodwin walked off the field with trainers to the locker room. He is expected to return for Tuesday's joint practices, according to coach Rex Ryan.
Goodwin left last Monday's practice with an illness after Ryan said Goodwin vomited on the field. The Bills' third-round pick in 2013 suffers from both sickle cell trait and asthma, although it's unclear if either played a role in his condition Monday.
Receiver Chris Hogan also left Monday's practice with heat-related issues while fellow receiver Sammy Watkins did not finish because of glute soreness. With receiver Marcus Thigpen working at running back because of several injuries at that position, the Bills were down to four healthy receivers at the end of Monday's practice: Robert Woods, Dez Lewis, Andre Davis and Deonte Thompson.
