Richmond has left out forward Daniel Rioli for Saturday night's Dreamtime clash against Essendon in Perth.
The triple premiership Tiger was an unused medical sub in last week’s win over Adelaide after being omitted following the Round 10 loss to Brisbane.
Rioli was also the medical sub against Sydney in Round 3 before he was dropped for Richmond’s Round 4 match against Port Adelaide.
He was also out of the side a couple of times in 2020 before rallying to play a key role in the club’s third flag in four years.
Tim Watson is curious as to why the 24-year-old is on the fringes in 2021.
“I see Daniel Rioli has been dropped again. He gets dropped a lot,” Watson told SEN Breakfast.
“Obviously he doesn’t do all the things that the little forwards are required to do there at Richmond.
“You think about (Jason) Castagna, when was the last time Castagna got dropped?”
Garry Lyon added: “He (Castagna) has had a bit of a lean trot. He scores his one or two (goals) along the way.
“There must be areas of his (Rioli's) game that they need to see him improve him.”
Rioli, who comes out of contract at the end of the year, has kicked eight goals in nine games and averages 3.2 tackles per match this season.
He’s booted 88 goals in 105 career games for the Tigers.
