The Lions training staff was looking at Broyles' right knee, not the left knee that suffered an ACL tear last year. Broyles has returned the sideline with an ice pack but will probably not return, according to John Niyo of the Detroit News.
Recently acquired Mike Thomas replaced Broyles at receiver. He was traded to the Lions from the Jacksonville Jaguars before the trade deadline this year.
The loss of the 5'10, 188-pound Broyles hurts especially because Detroit was already banged up at the receiver spot. Titus Young and Brian Robiskie are on the inactive list, leaving Calvin Johnson and tight ends Tony Scheffler and Brandon Pettigrew as the most reliable options for quarterback Matthew Stafford.
Broyles, a rookie from Oklahoma, has 21 catches for 307 yards this season. He also has two touchdowns.
