Adelaide forward Tom Lynch has been ruled out of Thursday night's blockbuster with Richmond at Adelaide Oval with illness, but skipper Taylor Walker is on track to play.

"He finished last season with some groin issues, and it's just a matter of how it settled over the break, and it wasn't to the level we wanted.
"When we started loading him back again, he started getting sore again.
"It's been ongoing and we've now got a clear plan.
"We had previous plans, but that hasn't yielded the result we want. Now that clear plan hopes to see him back out there in six to eight weeks."
