Wesco (calf) was listed as a non-participant on Tuesday's practice estimate.
Wesco has been unable to partake in any action since he injured his calf against the Packers back in Week 13, and his estimation as a non-participant during Tuesday's walk-through session doesn't bode well for his chances of suiting up this weekend against the Bills. If the fourth-year pro is unable to gain medical clearance before Saturday's matchup, Ryan Griffin should once again serve as Chicago's No. 2 tight end behind Cole Kmet.
