Jon Jansen could start at right tackle for the second week in a row as Stephon Heyer continues to come back from a shoulder injury.
Jansen started for Heyer in Sunday's 26-24 win over Dallas. It was his first extended action of the season and by all accounts he played well.
Heyer saw action in the Dallas game as a blocker on field goals, but he "tweaked" his shoulder again, Jim Zorn said.
"We just have to continue to get him up to speed," Zorn said.
Heyer's status for this Sunday's game against the Philadelphia Eagles will be determined later this week.
"Part of [the decision] will be Stephon's health, and part of it will be what decision we make in terms of who gets the nod," Zorn added.
Heyer, a second-year player out of Maryland, assumed the right tackle job in Week 1, beating out the veteran Jansen.
Asked if Jansen had performed well enough to earn back the starting job, Zorn replied: "I don't know about that. I think Jon stepped in and did a fine job. He was very aggressive in the run and he had no mental errors as aggressive as he plays."
Zorn noted that Jansen's pass protection showed improvement in the Cowboys game.
"He had a very strong outing," Zorn said. "It will be a very tough decision [as to who starts vs. the Eagles], but it has to be with all of the elements involved."
-- TAYLOR 'PROGRESSING WELL'
Jason Taylor is "on his way back" from a calf injury, but his availability for this Sunday's game against Philadelphia remains uncertain, Jim Zorn said.
A week ago, Taylor had a medical procedure to repair a calf injury suffered in the Redskins' Week 3 game against Arizona.
Taylor sat out Sunday's game at Dallas.
Team officials have called his status day to day.
"If it were up to Jason, he'd say, 'I'm playing,'" Zorn said. "But we truly don't know. I think things are progressing well, though."
-- SPRINGS' CALF
Shawn Springs suffered a calf injury during Sunday's game against Dallas, forcing him to sit out most of the second half.
Springs' availability for practice early this week is uncertain.
His injury is not considered serious, though.
Athletic trainers are "working on" the injury and the team hopes to have him ready for this week's game at Philadelphia.
