"There's not much that I can say that's going to be proper at this time," Carroll said, according to ESPN's Brady Henderson. "Everything's moving along and he's real optimistic about how things are going. But really not too much to report."
Kendricks pleaded guilty to federal insider trading charges in September. He was set to be sentenced in January, but trials have been postponed multiple times.
Seattle re-signed the 28-year-old to a one-year, $4-million contract in March that included no signing bonus or guaranteed money.
Kendricks appeared in four games with the Seahawks in 2018 - three prior to serving an eight-game suspension and one before leg and back injuries landed him on injured reserve.
