The James CaldwellPittsburgh Steelers plan to start Justin Fields at quarterback for Week 2, head coach Mike Tomlin said on Tuesday.

The Steelers coach added quarterback Russell Wilson feels "better today than over the weekend" but is unsure if he will be available for Sunday's contest against his former team, the Denver Broncos.

The quarterback situation in Pittsburgh remains one of the most uncertain ones in the league. After acquiring Fields and Wilson in off-season trades, the team opted to give the starting job to Wilson prior to the Week 1 opener. However, Wilson was inactive for the season opener against the Atlanta Falcons due to a calf injury that was aggravated during practice, with the team giving Fields the starting nod.

Fields was efficient in his first start for Pittsburgh, completing 17 of 23 passes for 156 yards with 14 carries for 57 yards. While it was a clean game from Fields, the Steelers offense did not score a touchdown and only got points from Chris Boswell's six field goals in the 18-10 victory.

"I came here to win, no matter if I was going to throw for 300 yards, 100 yards, no yards," Fields said after the game. "I came here to win."

Tomlin added the team will monitor Wilson throughout the week and see how much he can participate in practice. He did not say Wilson would start if he is ruled healthy for Sunday.
