The Washington Redskins are expected to place strong safety LaRon Landry on the season-ending injured reserve list with the fifth-year pro still hobbled by a bad left Achilles’ tendon and strained groin, according to a person with knowledge of the situation.

It would mark the second straight season that the free-agent-to-be would end the year on the injured list.

Landry has been plagued by the strained Achilles’ tendon for portions of the last two seasons, including the final seven games of last season. At the time that his 2010 season ended, Landry was on pace for a career year with 85 tackles, an interception and a forced fumble, and led all NFC strong safeties in Pro Bowl votes. Landry last offseason received both shockwave therapy and platelet-rich plasma treatments in hopes that the Achilles’ tendon would heal without traditional surgery.

Landry spent much of the preseason rehabbing to strengthen the tendon, and then it flared back up after the LSU product played seven straight games during the 2011 campaign.

Landry missed Washington’s Week 10 game against Dallas with the Achilles’ injury, returned the following week and strained his groin, and in the last two weeks has been unable to practice because of soreness both in the groin and Achilles’ tendons.

Redskins Coach Mike Shanahan on Wednesday had said he didn’t know about Landry’s availability the rest of the season, and then again on Thursday.

“I keep on thinking that [Landry is day-to-day], so I can’t tell you for sure. … Should know more tomorrow,” the coach said. “Even if he does come back, what speed can he practice at? What speed can he play at? Usually when a guy comes back after being away for a week or two weeks, it takes a little time to get back in football shape and play in a game.”

According to two people with knowledge of the situation, Shanahan met with Landry on Thursday morning to discuss the player’s health and the team’s course of action.

Around the same time on Thursday, while holding his weekly press conference, defensive coordinator Jim Haslett said that the team would be starting rookie DeJon Gomes at strong safety for the final three games of the season.
