Thornhill (calf) was designated to return from injured reserve Wednesday.
Thornhill missed Cleveland's last five games after sustaining a calf injury late in the Browns' Week 1 loss to the Cowboys, but it now appears he's nearing a return to the field. The 28-year-old's participation Thursday and Friday will be the best indication of whether he can return for the Browns' Week 7 matchup against the Bengals. However, Cleveland must still activate Thornhill to its active roster in order for him to suit up Sunday.
