Collaros, who was acquired from the Hamilton Tiger-Cats in January, suffered a concussion in Week 2 against the Ottawa Redblacks and has been sidelined until this week.
"(Collaros) is certainly going to play a bunch," Jones said after Tuesday's closed workout. "It doesn't matter (who will start). I know for sure Zach Collaros will play and Brandon Bridge, I'd say, will play a little bit too."
TSN's Matthew Scianitti reported that Collaros was working with doctors and neck specialists and has been feeling better over the past couple weeks.
Saskatchewan is 3-3 and sits fourth in the West Division.
