Grimes (hamstring) and Kennedy (concussion) both went down early Thursday night clash and now face a tough task of being ready for a short turnaround.
Tigers coach Damien Hardwick said he will await scans to determine his key back’s injury.
“We think it’s on the minor end of the scale but we will have scans tomorrow or the day following,” Hardwick said.
“Dyl’s had some history [with hamstring injuries], so we have just got to be mindful. He is so important for us, one of the best defenders in the AFL so we have got to make sure he is right for when the whip’s are cracking.
“We are very conservative with these types of injuries, he’s such an important player to the way we play. We just want to make sure when he is back he is right.”
Eagles coach Adam Simpson said the club wouldn’t push Kennedy’s concussion to be ready in time for their next game.
“It [four-day break] will make it difficult. Every case is different. We won’t be pushing it, whatever the docs say.” Simpson said.
Hardwick added he was happy with his teams endeavour in his clubs win.
“I was really pleased with our players’ endeavour,” he said.
“Especially our pressure … West Coast, if they get to play the game their own way they’re really damaging.
“Our key forwards were incredible [not letting the likes of Jeremy McGovern and Tom Barass mark]. They didn’t take a lot of marks between them but not getting out-marked which is really important.”
