PHOENIX -- Seattle Seahawks coach Pete Carroll talked Wednesday about some the team’s players who are coming off injuries.

He said the only two players who might not make it back for the start of the 2015 season are wide receiver Paul Richardson (ACL surgery) and nickelback Jeremy Lane (arm surgery and ACL surgery).

“That’s a long process to get back,’’ Carroll said of Lane, who suffered a compound wrist fracture and a knee-ligament tear on his interception in the Super Bowl. “It’s about how he handles the final stages of it.”

Richardson, a rookie last season out of Colorado, tore his ACL in the playoff game against Charlotte. He also tore the same ACL while in college.

“We’re hearing he’s doing exceedingly well,” Carroll said of Richardson. “His mentality is good. He’s been through it before so he knows the staging and all that. We expect him to have a full recovery.”

The Seattle secondary is a banged-up bunch, but Carroll said things look good for free safety Earl Thomas and cornerback Tharold Simon, both of whom has shoulder surgery.

“Everything we’re hearing is things are going really well and the surgeries were very successful,” Carroll said. “There’s just a time frame we have to make it through.”

Thomas had surgery for a torn labrum. Carroll was asked if he expects Thomas will be ready to go by September: “Oh, yeah, certainly.”

Kam Chancellor is recovering from a torn MCL in his left knee and cornerback Richard Sherman is recovering from a torn elbow ligament.

Carroll also said 2014 rookie defensive end Cassius Marsh is 100 percent healthy after suffering a broken foot in October.

“He’s in great shape,” Carroll said of Marsh. “That’s a tremendous addition. It’s like a brand new draft choice for us because he didn’t really get a chance to get started last year. Cassius is a really high-energy, creative and productive football player. We can’t wait to get him out there. He’s in great shape and looks terrific.”
