The Bears on Saturday placed right guard Kyle Long on injured reserve with a right foot injury he sustained late in last Sunday's win over the New York Jets at Soldier Field.
Coach Matt Nagy said Wednesday that the injury involves a tendon and is not related to the broken right ankle Long suffered Nov. 13, 2016 in a loss to the Buccaneers in Tampa.
Long must remain on injured reserve for eight weeks, making him eligible to return to the active roster for the Bears' season finale Dec. 30 against the Vikings in Minnesota.
NFL Network insider Ian Rapoport reported Tuesday night that Long is expected to be sidelined 6-8 weeks, but the Bears have not provided a timetable for his return.
Selected by the Bears with the 20th pick in the 2013 draft, Long was voted to the Pro Bowl in each of his first three seasons while starting 47 of 48 games. But he missed 14 contests in 2016-17 due to injuries and spent this past offseason recovering from surgeries on his neck, shoulder and elbow.
The Bears filled Long's roster spot Saturday by elevating running back Taquan Mizzell Sr. from the practice squad to the 53-man roster. Mizzell entered the NFL last year as an undrafted free agent with the Ravens out of Virginia and played in three games for the Bears in 2017 as a rookie.
