Bears linebacker Leonard Floyd left the field on a cart as Chicago opened its first day of practice on Thursday.
Head coach John Fox said that Floyd’s departure was a result of him being sick, not an injury.
One source told Pro Football Talk that Floyd began to feel woozy during practice as a result of the heat.
The Bears traded up in the NFL draft to selected Floyd with the No. 9 pick. He was expected to complete for a starting role in the Bears' defensive lineup along with Pernell McPhee, Willie Young and Lamarr Houston. The team was also pleased with the condition and shape he arrived in, weighing in at 240 pounds.
In his three years at Georgia, he collected 17 sacks and 182 tackles.
The Bears are coming off a 6–10 season, when they finished fourth in the NFC North and did not reach the playoffs for the fifth straight year.
