J’Marcus Webb is likely to get his second straight start at right guard for Seattle in place of first-round pick Germain Ifedi.

Webb started in place of an injured Ifedi last week for Seattle’s season opener against the Miami Dolphins. After struggling against Ndamukong Suh last week, Webb will be tasked with trying to block Aaron Donald in the Los Angeles Rams home opener.

“Still learning how to do it, which is a big improvement from last week,” offensive line coach Tom Cable said of Webb. “Had some struggles but I think he’s better this week for sure.”

Ifedi had been the starting option at right guard from the moment he was drafted. Along with center Justin Britt and left guard Mark Glowinski, Seattle’s interior three linemen played strong throughout the preseason. Ifedi’s ankle injury in practice stunted that progress. While he hasn’t been ruled out, head coach Pete Carroll admitted it’s unlikely he’ll be back in time for the Rams.

“It’s going to be a challenge for him to make it back this week,” Carroll said. “I don’t think he’s canceled it out yet, but we’ll see what happens.”

Ifedi did not participate in the team’s practice on Wednesday.
