Thompson (knee) isn't listed on Monday's estimated injury report, Darren Urban of the Cardinals' official site reports.
The 23-year-old was inactive for Sunday's win over the Bills due to the knee issue, so it's a bit of a surprise to see him absent from the injury report only a day later. Thompson should fill a reserve role Thursday against the Seahawks, but he could have a larger workload if Budda Baker (groin) or Jalen Thompson (shoulder) are unable to play.
