Ailing quarterback Russell Wilson intends to increase his participation in practice and put behind him the calf injury keeping him out of the Pittsburgh Steelers' lineup. Steelers head coach Mike Tomlin remains steadfast in his approach to involving Wilson in Pittsburgh's plans. He first wants Wilson to prove he's healthy. Tomlin said Tuesday that Wilson would "pick up" practice participation after being inactive for the first four games of the season. He strained his calf in training camp, giving former Chicago Bears first-round pick Justin Fields more time than expected with the starting offense. Wilson was named the starter following the final preseason game in August, but was limited in practice before the Week 1 opener at Atlanta. His status did not change in September, when Fields led the Steelers to a 3-1 start. Fields again is preparing to start for the Steelers against the Dallas Cowboys (2-2) on Sunday. Until Wilson gets on the field and completes practice as a full participant, Tomlin won't be addressing whether Fields could possibly keep the job when both quarterbacks are healthy. "There's a potential for that, but we're not there as we stand here today," Tomlin said Tuesday. Tomlin said Tuesday the Steelers are optimistic guard Isaac Seumalo (pectoral) and linebacker Nick Herbig (ankle) will be ready when the Cowboys visit Sunday night. He's not as certain about running back Jaylen Warren and said linebacker Alex Highsmith is out for the second game in a row with a groin injury. Seumalo's return would be timely following the likely season-ending Achilles injury to James Daniels at Indianapolis. Daniels was ruled out by Tomlin, but the Steelers have not yet placed the veteran guard on injured reserve. Three of the Steelers' next four games are in primetime. Pittsburgh lost for the first time this season at Indianapolis last week. Fields had 312 yards passing and ran for 55 yards with two TDs, leading the offense to touchdowns on three consecutive drives after a costly fumble trying to evade a sack nearly 20 yards behind the line of scrimmage. Tomlin gave his first harsh assessment of Fields on Sunday night after the loss to the Colts. "Appreciate his fight, but he and we were a little bit sloppy at times. Too sloppy to secure victory," Tomlin said. Wilson last started a game on Christmas Eve before the Denver Broncos benched him for the final two regular-season games in a contract dispute that led to the former Super Bowl winner being released. He signed with the Steelers in March after also visiting the New York Giants. --Field Level Media
